摘要
介绍了多维格状编码调制 (MTCM)及其自适应格状编码调制的设计方法 。
This paper gives an introduction of multidimentional trellis coded modulation scheme and the method to design Rate compatible trellis codes for Rayleigh fading channel,and compares the BER(bit error rate) performance between the fixed rate TCM schemes and the rate compatible one in Rayleigh fading channel.
