摘要
首先介绍了基于信道编码的多级编码调制(MLC)的原理与特点;其次,重点论述了MLC的多级译码(MSD)和并行译码(PDL)方法;最后,以BCH为分量码并针对在高斯信道和瑞利衰落信道,分别给出MLC的MSD与PDL两种译码结果。
In this paper, we introduced the principle and characteristics of multilevel coding in the area of channel coding. Then we discussed the method of multistage decoding（MSD） and parallel decoding on levels（ PDL） in particular. Finally,by using the BCH codes in the MLC system,we presented the perfomance of MSD and PDL on the the Gaussian channel and Rayleigh fading channel.
