摘要

实用栅格编码调制(TCM)使用行业标准，64状态，二进制卷积码。给出了一种有效实现速率2/3编码8相移键控(PSK)的实用TCM系统的逻辑设计和仿真结果。该系统将量化相位接收器的每个扇区与一对权重相关联，作为维特比解码器的软决策输入。该系统在误码率为10/sup -5/及以下的情况下接近3db的编码增益。

Pragmatic trellis coded modulation: a simulation using 24-sector quantized 8-PSK

Pragmatic trellis coded modulation (TCM) uses the industry standard, 64-state, binary convolutional code. The authors present the logic design and simulation results for a system which effectively implements pragmatic TCM for rate 2/3 encoded 8 phase shift keying (PSK). This system associates each sector of a quantized phase receiver with a pair of weights to be used as soft decision inputs of the Viterbi decoder. This system approaches 3 dB of coding gain at bit error rates of 10/sup -5/ and less.<>
