摘要: 本文討論了分組碼的格圖結(jié)構(gòu),給出了某些BCH碼L段格圖結(jié)構(gòu),并據(jù)此提出了BCH碼的快速最大似然譯碼算法,同時(shí)討論了qm元分組碼的q元映象的譯碼問題,給出了q元映象的直和劃分結(jié)構(gòu)和相應(yīng)的譯碼算法。

Abstract: Trellis structures of block codes are discussed. L-section trellis structures of some BCH codes are presented. A fast maximum likelihood decoding algorithm for BCH codes is proposed correspondingly, Decoding porblem of q-ary images of qm-ary block codes is also discussed. The direct sum partition and the associated decoding algorithms are given for the images. -
