摘要

本文研究了具有分集的栅格编码8-PSK的性能。假设TCM的“实用”方法，其中代码是使用公共速率1/2约束长度7编解码器构造的。利用软符号组合形式的分集，在串联TCM/分集调制中获得了约2 ~ 3db的性能改进。

TCM and diversity in a Rayleigh fading channel

The performance of trellis coded 8-PSK with diversity is examined in the paper. The "pragmatic" approach to TCM is assumed, where the code is constructed using a common a rate 1/2 constraint length 7 codec. Using diversity in the form of soft symbol combining in a concatenated TCM/diversity modulation, a performance improvement of about 2 to 3 dB was obtained.
