Abstract

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.
