| 摘 要： | 本文提出了在移动衰落信道中设计多级编码(MLC)方案的一种非欧度量:"信道容量规则"+"映射规则".在AWGN信道中为:"信道容量规则"+"UP(Ungerboeck Partitioning) 规则";在Rayleigh衰落信道中为:"信道容量规则"+"BP(Block Partitioning)规则".并在此理论指导下,选用不同码长的BCH码作为MLC系统中各级分量码,通过计算机模拟,比较了在AWGN和Rayleigh衰落信道中,采用8ASK调制方式、多级译码(MSD)、三种不同映射方法下的三级MLC方案的性能.

| Abstract: | A non-Euclidean metric which is “capacity Rule” and “mapping Rule” for the design of optimal MLC scheme over mobile fading channels is proposed. For AWGN channels, it is “capacity rule” and “UP rule”. For Rayleigh fading channels, it is “capacity rule” and “BP rule” .Directed by this theory,the performance of three levels multilevel coding with multistage decoding (MLC/ MSD) scheme in AWGN and Rayleigh fading channels is simulated. In which BCH codes with different code lengths are chosen as component codes,and three mapping strategies with 8ASK modulation are used. |

| Keywords: | mobile fading channel multilevel coding capacity rule non Euclidean metrit |
