  • Dual-wideband dual-polarised magnetoelectric dipole antenna for 4G/5G
           microcell base station
    • Authors: Congcong Zhu;Bin Wang;Wei Luo;Honggang Hao;Ping Wang;
      Pages: 269 - 271
      Abstract: A novel dual-wideband dual-polarised magnetoelectric (ME) dipole antenna for the fourth generation (4G)/fifth generation (5G) microcell base station is proposed. Using a pair of orthogonal ME dipoles and Γ-shaped tapered cross feeding lines, the initial antenna achieves dual-band and dual-polarised. Then, four U-shaped gaps, added in electric dipoles, effectively extend the lower impedance bandwidth. Finally, a circular parasitic patch with capacitive properties is innovatively loaded above the ME antenna, which obviously reduces the high-resonant frequency from 5.5 to 4.9 GHz. Meanwhile, a box-shaped reflector is employed to achieve stable gain and radiation patterns. As a result, the measured results show the good dual-wideband performance of 52.4% (2.14–3.66 GHz) and 7.4% (4.68–5.04 GHz) with voltage standing wave ratio (VSWR) < 2, high isolation (>25 dB) and high gain (9.5 and 5.5 dBi, respectively). In addition, a stable radiation pattern with a half-power beam width of $63.5^circ pm 6.8^circ $63.5°±6.8° and good cross-polarisation discrimination (>20 dB) on the E-plane is realised over these two bands.

  • Low-profile broadband aperture coupled magneto-electric dipole array
           antenna for millimetre-wave applications
    • Authors: Guopeng Yang;Jinping Zhang;Zhipeng Zhou;
      Pages: 271 - 273
      Abstract: This Letter presents a low-profile broadband cavity-backed magneto-electric (ME) dipole antenna fed by a substrate integrated waveguide aperture. To reduce the antenna profile, a U-shaped slot is etched on the electric dipole. Compared to the traditional ME dipole antenna whose profile is generally $0.25lambda _varepsilon $0.25λε, the thickness of the proposed radiation structure is $0.13lambda _varepsilon $0.13λε, where $lambda _varepsilon $λε is the wavelength in the dielectric substrate. A $4 times 4$4×4 array antenna with the proposed antenna as its element is then designed, simulated and fabricated. With the return loss is below −10 dB, a 19.1% (30.3–36.7 GHz) impedance bandwidth has been achieved. The radiation pattern of the proposed array antenna is quite stable, and the peak gain varies below 1 dB withi- the operating band.

  • Metallic reflectors with notched RCS spectral signature using dielectric
    • Authors: A. Alhaj Abbas;M. El-Absi;A. Abuelhaija;K. Solbach;T. Kaiser;
      Pages: 273 - 276
      Abstract: Dielectric resonators are placed in front of the metallic plane plate and corner reflectors. Excitation of the resonant mode produces strong scattering of an incident plane wave which shows up as narrow notch in the mono-static radar cross section (RCS) spectral signature at the resonance frequency. Experimental proof at V-band is given with a corner reflector of centimetre size with spherical dielectric resonators of 0.8 mm diameter showing a notch at 64 GHz.

  • 300-GHz integrated heterodyne receiver with carrier lock-in Costas loop
    • Authors: C. Yi;S.-H. Choi;M. Kim;
      Pages: 276 - 278
      Abstract: A carrier signal lock-in experiment using a 300-GHz integrated heterodyne circuit is presented. The circuit contains a single voltage-controlled oscillator with a single set of quadrature mixers that are fabricated using 250-nm InP double hetero-junction bipolar transistor technology. An external feedback loop containing packaged baseband components such as amplifiers, a phase discriminator, and a filter is connected to the integrated circuit to form a complete receiver system. For a −25 dBm of input RF signal with 3.5-GHz single-tone carrier-suppressed modulation, the receiver system responds with successful lock-in range of 110 MHz centred around 311 GHz.

  • High-efficient superblock flash translation layer for NAND flash
    • Authors: Peiyong Zhang;Huanjie Tang;
      Pages: 278 - 280
      Abstract: Flash controller is the core hardware embedded in today's mobile device storage, and the flash translation layer (FTL) is the key system of controller. This Letter proposes a high-efficient superblock FTL (HSPB) to satisfy the demand of large media files and application files storage, which implements the cross-block sequential writing strategy and the shared cached mapping table scheme. Test results show that HSPB reduces the time and power consumption by 7–30% in seq/random write and gains up to 60% improvement in sequential/random read compared to other FTLs.

  • Radio frequency reliability studies of CMOS RF integrated circuits for
           ultra-thin flexible packages
    • Authors: D. Mitra;S.B. Hamidi;P. Roy;C. Biswas;A. Biswas;D. Dawn;
      Pages: 280 - 282
      Abstract: This Letter presents for the first time radio frequency (RF) reliability studies of fully integrated CMOS RF integrated circuits (RFICs) for next generation wireless communication applications involving conformal bodies where wireless communication RFICs will be embedded on ultra-thin flexible packages. As a test case, RF characteristics of a CMOS voltage-controlled oscillator (VCO) chip with multiple die-substrate thicknesses were measured and results are analysed. The CMOS VCO chip under study was designed and fabricated using 180 nm RF-CMOS process. Reliability of performances of the VCO chips are characterised and results are compared before and after die thinning from 250 to 50, 35, and 25 μm, respectively. Critical RF performance parameters such as frequency of oscillation, output power, and phase noise are considered for analysis, respectively. All the dies are placed face-up for probing on the top of a metal chuck with ground connection inside the micro-chamber of a probe station. While the deviations of frequency and output power are within ±1% and ±1 dB, respectively, due to the die thinning affect, the phase noise deteriorations are observed significant. It confirms the well-known fact of phase noise sensitiveness to the substrate thickness due to the leakage and SOI CMOS is discussed widely to minimise these parasitic effects.

  • Self-biased nano-power four-transistor current and voltage reference with
           a single resistor
    • Authors: H. Aminzadeh;
      Pages: 282 - 284
      Abstract: A generic nano-power voltage and current reference topology, which takes advantage of the unequal threshold voltage ($V_{{rm TH}}$VTH) of two MOSFETs in subthreshold region, is developed to provide reliable bias and reference signals for the analogue integrated blocks used in the Internet-of-Things applications. The new architecture is a self-powered four-transistor topology with a single temperature-insensitive resistor, generating both temperature-independent voltage and current without any operational amplifier or bias network. Instead, the resistor defines the absolute value of the current reference ($I_{{rm REF}}$IREF) which supplies the core devices. The circuit is designed and simulated for a target current reference of 7.50 nA in 0.18 µm CMOS process, and achieves a worst-case temperature coefficient (TC) of 59.47 ppm/°C over a temperature range from −40 to 125°C and 1.8 V voltage supply. The average voltage reference ($V_{{rm REF}}$VREF) is 346 mV, and the worst-case TC of differen- corners is 21.98 ppm/°C. The nominal current consumption is twice the $I_{{rm REF}}$IREF (15 nA) regardless of the supply and temperature, and can be scaled down by reducing the desired current reference.

  • New fault-tolerant control method for Hall signals in brushless DC motor
           driver of E-bicycle
    • Authors: Yi Zhang;Hao-Chen Wang;Hai-Feng Wei;Yuan-Jiang Li;Ke-Li Li;Wei-Ting Liu;
      Pages: 284 - 286
      Abstract: A new fault-tolerant control method for Hall sensors in brushless DC motor driver of E-bicycle is presented. Contrary to the classical fault-tolerant control method that focused their attention on fault diagnosis, the proposed method uses pulse-width modulation input capture function to extract sensors' effective information and eliminate fault information, which helps to omit the process of fault diagnosis and improve the efficiency of fault-tolerant control. The effective information of Hall sensors includes edge jump information and velocity information, which are used to correct and estimate the rotor angle under field oriented control. The effectiveness and rapidity of the proposed fault-tolerant approach are illustrated through experimental results.

  • Methodological approach for workspace boundary determination in joint
           space using support vector machine
    • Authors: W. Seol;K.-S. Kim;S. Kim;
      Pages: 286 - 288
      Abstract: For most industrial robots using position control, self-collision is a headache. Without well-defined constraints at a joint level, self-collision can lead to damage to a robot or even injury to the operator. In this study, a new methodological approach is proposed that is different from the traditional methods of using sensors or analysing kinematics. The proposed method uses a support vector machine to construct a joint boundary map based on the robot's movement in the workspace. To verify its feasibility and performance, simulations are conducted. The proposed method is believed to help reduce the cost and computational burden. It is expected to be utilised even in applications where the existing methods are difficult to use.

  • Deblocking performance analysis of weak filter on versatile video coding
    • Authors: J. Lee;J. Jeong;
      Pages: 289 - 290
      Abstract: The deblocking filter of the versatile video-coding (VVC) standard is included in the form of an in-loop filter, as a high efficiency video coding (HEVC) standard. The specifics of the deblocking filter of the VVC remain unchanged from that of the HEVC standard. The presence and type of deblocking filter depend on the quantisation parameters and the conditions of the block boundary. There is a far greater complexity owing to the calculations for boundary condition checks. To verify the enforcement conditions of the weak filter and the filter effectiveness, to propose an efficient judgement condition and to improve the filter are attempted. The scope for improvement of the parameters of the conventional in-loop filter is evaluated and that the compression efficiency of the weak filter part should be improved is proposed.

  • Point-selection and multi-level-point-feature fusion-based 3D point cloud
    • Authors: Qieshi Zhang;Jun Cheng;Shengwen Wang;Chengjun Xu;Xiangyang Gao;
      Pages: 290 - 293
      Abstract: Recent years, the research on object classification based on three-dimensional (3D) point cloud pays more attention to extract the features from point sets directly. PointNet++ is the latest network structure for 3D classification which has achieved acceptable results. Although it has achieved acceptable results, there are still two problems: (i) The farthest point sampling (FPS) algorithm in PointNet++ ignores the fact that the feature of each point contributes differently to the classification and segmentation tasks. Therefore, FPS cannot guarantee that the selected point sets can correctly represent the main features of the object. (ii) The multi-scale grouping and multi-resolution grouping in PointNet++ do not consider the features between different levels of the same point. In order to solve these problems, the authors propose the point-selection structure which can calculate the importance of each point's feature. In addition, multi-level-point-feature fusion module is proposed to extract the features of the point at all levels and fuse them as a new feature of that point. In this Letter, they make some experiments on ModelNet40 and ScanNet datasets, which achieves better results compared to the state-of-the-art methods.

  • Polarimetric SAR image despeckling using bandelet transform based on
           additive–multiplicative speckle model
    • Authors: T. Roy;R. Sethunadh;P.M. Ameer;
      Pages: 293 - 296
      Abstract: Efficient speckle filtering algorithms are required for the effective use of polarimetric synthetic aperture radar (SAR) technology in remote sensing and surveillance applications. Nevertheless many techniques have been proposed over the past two decades to decrease the speckle noise in polarimetric SAR images, they are all based on the multiplicative speckle noise model. In order to fully utilise the advantages of polarimetry of these images, an additive–multiplicative noise model is explored. Coupled with this, bandelet based Bayesian thresholding is used to tap the advantages of transform domain filtering. Here the elements of the covariance matrix are processed differently for diagonal and off-diagonal elements to achieve maximum benefits. The proposed filtering scheme is evaluated using airborne and spaceborne polarimetric images and compared against state-of-the-art techniques. Results indicate that the proposed method reduces the speckle content while retaining the geometrical features in these images.

  • Adversarial shared-private networks for specific emitter identification
    • Authors: Peibo Chen;Yulan Guo;Gang Li;Jianwei Wan;
      Pages: 296 - 299
      Abstract: Deep learning provides a new scheme for specific emitter identification (SEI). However, most deep learning-based methods directly apply existing neural networks in other fields to SEI without considering its particularity. The identification-relevant information only accounts for a small proportion of the information carried by the received signal, and thus is easily interfered by the rest identification-irrelevant information during its mining process. This Letter proposes adversarial shared-private networks (ASPN) to address the most challenging case where all emitters are of the same type. By separating the normalised signal bispectrum amplitude and phase in the first quadrant into two orthogonal components, one that is shared among all emitters and the other that is private to each emitter, ASPN extracts more effective features and achieves more remarkable performances than most methods in the literature.

  • Investigation of radiation recovery effect on sensing fibre in BOTDR
    • Authors: Mi Li;Yizhuo Zhang;Zhang Chen;You Guo;Xinyu Zhang;Xuping Zhang;
      Pages: 299 - 301
      Abstract: The radiation recovery effect on sensing fibre in Brillouin optical time-domain reflectometer (BOTDR) has been experimentally investigated. In the experiment, three kinds of commercial single-mode G.652.D fibres: Yangtze Optical Fibre and Cable, Corning and Fujikura have been used as sensing fibre in BOTDR system. After 200 Gy dose gamma-ray radiation absorbed by sensing fibre, the performance of BOTDR at different time intervals has been tested. Moreover, by analysing Brillouin gain spectra along with fibre sample, the recovery in radiation-induced attenuation, the variation of Brillouin frequency shift and the variation of stress coefficient are characterised. The results will be helpful for the error correction in the simulation experiment and are a reliable basis for the introduction of BOTDR into the space station.

  • Two-UAV trajectory planning for cooperative target locating based on
           airborne visual tracking platform
    • Authors: Cheng Xu;Chanjuan Yin;Wei Han;Dongzhen Wang;
      Pages: 301 - 303
      Abstract: Two-unmanned-aerial-vehicle (UAV) cooperative target locating based on airborne visual tracking platform is a common UAV reconnaissance mode. In the process of two-UAV cooperative target locating, the performance of target locating is highly dependent on UAV trajectory. In this Letter, a trajectory planning method for two-UAV cooperative target locating is presented. Using the line-of-sight (LOS) targeting property of the airborne visual tracking platform, in combination with the azimuth angle and elevation angle of the measured LOS, a locating error model is established, which can reflect the correlation between the target locating error and LOS angle error. Then an objective function based on minimising the target locating error is built, which is used as an index of two-UAV trajectory planning. This method can be applied in two-UAV trajectory planning for cooperative target locating and the simulated results confirm that it works effectively.

  • Optical classifier based on volume holographic filter with vector
    • Authors: K. Ikeda;H. Fujiyoshi;M. Yamada;E. Watanabe;
      Pages: 303 - 305
      Abstract: A new implementation of the weight vector in a classifier based on an optical system using a volume holographic filter with a vector decomposition algorithm is proposed for high-speed data classification. Using a volume holographic filter, the correlation between the input and the decomposed weight vector is calculated for the classification score, which is the output from the decision function in the optical classifier. The authors experimentally demonstrate the core concept and confirm the effectiveness of the proposed method by executing a two-class classification problem using a volume hologram medium.

  • A novel sufficient condition to avoid subharmonic oscillations for buck
           converters with constant on-time control
    • Authors: F. Bizzarri;P. Nora;A. Brambilla;
      Pages: 305 - 308
      Abstract: Fast transient response, simple control scheme and low cost are features that distinguish constant-on-time buck converters from others. Simplicity of the control scheme is reflected in a single requirement for power electronics engineers: a design that ensures enough low amplitude resistive ripple component at the feedback to precisely starts the on-time pulse. There are design rules that guide the selection of the components. A well known one reported in the literature predicts if the converter suffers of the sub-harmonic oscillations undesirable phenomenon. The authors present a better simple design expression to avoid the onset of this unwanted drawback.

  • Integrated 100 V bootstrap diode with enhanced reverse recovery
           characteristics for eGaN-field effect transistor gate drivers
    • Authors: Shaohong Li;Jing Zhu;Weifeng Sun;Long Zhang;Yanqin Zou;Guichuang Zhu;Tian Tian;
      Pages: 308 - 309
      Abstract: An integrated 100 V bootstrap diode (DBST) with anode engineering based on the double epitaxial process for enhancement mode gallium nitride (eGaN) transistor gate drivers is first proposed in this Letter. On the anode side, the P + dynamic field limiting ring (PDFLR) and the floating metal electrode (FME) are employed. The PDFLR can greatly suppress the peak electric field on both sides of the device during the reverse recovery period, which leads to a significant improvement in reverse recovery robustness. The FME lowers the anode injection efficiency in on-state and increases the hole recombination rate during reverse recovery, therefore, a fast reverse recovery is realised. The partial heavy doped N-type buried layer not only reduces the resistance of the drift region but also shortens the hole extraction path from the drift region to sub-electrode, as a result, reverse recovery tail current can be greatly shortened. Experiments combined with simulations show that the reverse recovery robustness of the optimised proposed DBST is improved by more than 12 times. Furthermore, the reverse recovery charge (Qrr) of the proposed structure is only 3.2 nC, which is 22% lower than that of the conventional device at the same forward current (IF) of 0.1 A.

  • Joint Viterbi detection and decoding algorithm for bluetooth low energy
    • Authors: Chulhyun Park;Yongchul Jung;Jihoon Kim;Yunho Jung;
      Pages: 310 - 312
      Abstract: An efficient joint Viterbi detection and decoding (JVDD) algorithm for a bluetooth low energy (BLE) system is proposed. Since the convolutional coded Gaussian minimum-shift keying (GMSK) signal is specified in the BLE 5.0 standard, two Viterbi processors are needed for detection and decoding. However, the proposed JVDD scheme uses only one Viterbi processor by modifying the branch metric with inter-symbol interference information from GMSK modulation; therefore, the hardware complexity can be significantly reduced without performance degradation.
