摘要

基于信道容量规则和分组分割

构造自适应于AWGN和Rayleigh两种信道特征的多级编码系统

分量码选用删除型卷积码

系统性能与未编码系统和BCH码为分量码的系统作比较.在多阶段译码中提出利用信道状态信息的软判决支路度量计算公式

比较软、硬判决译码对系统性能的影响

为移动信道编码调制系统的最佳设计度量提供参考.

Abstract

Based on Capacity Rule and Block Partitioning (BP) strategy

a robust Multilevel Coding (MLC) scheme is proposed for AWGN and Rayleigh fading Channels using punctured convolutional codes.The system performance is compared with that of the uncoded 4ASK system and the MLC with BCH codes.The formulations for computing the soft decision metrics with Channel State Information (CSI) are presented for multistage decoding (MSD) and the performance comparisons are made for soft and hard decision decoding.The research can present some references for the optimal design of Multilevel Coding schemes.
