重复累积码几种译码算法的研究

Research of Different RA Decoding Algorithms

介绍了一种可以进行线性编码、线性译码的好码──重复累积码,分析和推导了基于Tanner图的三种译码算法,用MATLAB在高斯信道下对三种算法进行仿真,对RA码译码的结果进行了比较。

This paper introduces a kind of good code called repeat accumulate code which can be linear coding and linear decoding. Analysis and derivation of three decoding algorithms are made based on Tanner graph. We simulate the three RA decoding algorithms in the AWGN channel by MATLAB and make comparisons of the different decoding performance.
