8状态8PSK TCM在多径衰落信道中的应用

An Application of 8 States 8PSK Trellis Coded Modulation to Multi-diameter Fading Channel

介绍了网格编码调制(TCM-TrellisCodedModulation)的基本原理,提出了采用(3,2,3)卷积码与8PSK结合构成8状态8PSK网格编码调制的方案,并对其在多径衰落移动信道中应用的性能进行了分析,推证了8状态8PSK网格编码调制对信道性能的改善。

This paper introduces the principle of Trellis Coded Modulation and the key technique, presents a TCM case of convoluted code word combined together with 8 states 8PSK, analyzes the capability of this system under the conditions of multi-diameter fading channel and proves the improvement made by 8 states 8PSK TCM on the performance of mobile channel.
