摘要：

A new trellis decoding method of block codes based on the GAC structure is applied to Rayleigh fading channels in this paper. Performance of this decoding technique with hard-decision and soft-decision is studied respectively. Researches are also carried out to introduce this maximum-likelihood decoding method to narrow-banded mobile image transmission systems.
