  • Skew cyclic and skew (α1 + uα2 + vα3 + uvα4)-constacyclic codes over
           Fq + uFq + vFq + uvFq
    • Authors: Habibul Islam, Om Prakash
      Pages: 101 - 116
      Abstract: In this note, we study skew cyclic and skew constacyclic codes over the ring <i>R</i> = <i>F<SUB align="right">q</i> + <i>uF<SUB align="right">q</i> + <i>vF<SUB align="right">q</i> + <i>uvF<SUB align="right">q</i> where <i>q</i> = <i>p<SUP align="right">m</SUP></i>; <i>p</i> is an odd prime, <i>u</i><SUP align="right">2</SUP> = <i>u</i>, <i>v</i><SUP align="right">2</SUP> = <i>v</i>, <i>uv</i> = <i>vu</i>. We show that Gray images of a skew cyclic and skew-constacyclic codes of length <i>n</i> over <i>R</i> are skew quasi-cyclic codes of length 4<i>n</i> over <i>F<SUB align="right">q</i> of index 4. Also, it is shown that skew <i>α</i>-constacyclic codes are either equivalent to <i>α</i>-constacyclic codes or <i>α</i>-quasi-twisted codes over <i>R</i>. Further, structural properties, specially, generating polynomials and idempotent generators for skew cyclic and skew constacyclic codes are determined by decomposition method.
      Keywords: skew polynomial ring; skew cyclic code; skew quasi-cyclic code; skew constacyclic code; Gray map; generating polynomial; idempotent generator

  • An iterative decoding scheme on random burst error correction with
           Reed-Solomon codes
    • Authors: Habibul Islam, Om Prakash
      Pages: 117 - 129
      Abstract: We investigate the decoding scheme of conventional Reed-Solomon (R-S) codes, and propose a systematic model to achieve better decoding results on random burst error corrections. We follow the iterative decoding procedure and verify this decoding model by implementing a typical R-S (15, 9) code, then present complexity analysis of this decoding model on the improvements for burst error correction. Simulations on several examples of R-S codes display the validity of this decoding scheme.
      Keywords: Reed-Solomon (R-S) code; burst error correction; decoding

  • Constacyclic codes over the ring Fp + vFp and their applications of
           constructing new non-binary quantum codes
    • Authors: Yongkang Wang, Jian Gao
      Pages: 130 - 141
      Abstract: In this paper, we study some results on constacyclic codes over F<SUB align="right"><i>p</i> + <i>v</i>F<SUB align="right"><i>p</i>, where <i>p</i> is an odd prime and <i>v</i><SUP align="right">2</SUP> = <i>v</i>. Under some special Gray map, the image of the (<i>α</i> + <i>βv</i>)-constacyclic code over F<SUB align="right"><i>p</i> + <i>v</i>F<SUB align="right"><i>p</i> is a (−<i>α</i>(<i>α</i> + <i>β</i>))-constacyclic code over F<SUB align="right"><i>p</i>, where <i>α</i> and <i>β</i> are non-zero elements of F<SUB align="right"><i>p</i> satisfying <i>β</i> = −2<i><i>α</i></i>. As an application, some new non-binary quantum codes are obtained.
      Keywords: constacyclic codes; Gray map; new non-binary quantum codes

  • Self-dual codes over Z4[x]/(x2 + 2x) and the
           Z4-images
    • Authors: Bahattin Yildiz, Abidin Kaya
      Pages: 142 - 154
      Abstract: In this work, constructions for self-dual codes over the ring Z<SUB align="right">4[<i>x</i>]/(<i>x</i><SUP align="right">2</SUP> + 2<i>x</i>) are considered together with their images under an orthogonality-preserving grey map, which result in self-dual Z4-codes. Theoretical results about the existence/non-existence of self-dual codes from construction methods such as the double circulant, bordered double circulant and four circulant matrices for the rings Z<SUB align="right">4 and Z<SUB align="right">4[<i>x</i>]/(<i>x</i><SUP align="right">2</SUP> + 2<i>x</i>) are given. The construction methods are then applied to get good self-dual Z<SUB align="right">4-codes of lengths 16, 32, 48 and 64 (including some extremal type I and type II codes), which are tabulated at the end.
      Keywords: self-dual codes; codes over rings; grey maps; double-circulant codes; bordered double circulant codes; four circulant codes

  • A study of cyclic and constacyclic codes over Z4 + uZ4 + vZ4
    • Authors: Habibul Islam, Om Prakash
      Pages: 155 - 168
      Abstract: In this paper, we study some properties of cyclic and constacyclic codes over the ring <i>R</i> = Z<SUB align="right">4 + <i>u</i>Z<SUB align="right">4 + <i>v</i>Z<SUB align="right">4 where <i>u</i><SUP align="right">2</SUP> = <i>uv</i> = <i>vu</i> = 0. The generator polynomials and minimal spanning set for cyclic codes over <i>R</i> are determined. Further, (1 + 2<i>u</i>) - constacyclic codes are considered and find the cyclic, quasi-cyclic and permutation equivalent to a QC code over Z<SUB align="right">4 as the Gray images of (1 + 2<i>u</i>) - constacyclic codes over <i>R</i>.
      Keywords: cyclic code; minimal spanning set; constacyclic code; quasi-cyclic code; Gray map

      Abstract: A series of maximum distance quantum error-correcting codes are developed and analysed. For a given rate and given error-correction capability, quantum error-correcting codes with these specifications are constructed. The codes are explicit with efficient decoding algorithms. For a given field maximum length quantum codes are constructed.
      Keywords: quantum code; maximum distance separable; MDS
