摘要
基于译码算法是影响新型信道编码方案Turbo码性能的主要因素之一,分析研究了Turbo码的译码算法,并对其几种译码算法进行了比较,用Matlab得出了仿真下的性能特性曲线。根据Turbo码编码结构和迭代译码的特点,还对Log-MAP算法进行了改进。
In view of decoding algorithm as one of the major factors influencing Turbo coding, a new channel coding plan, this paper analyzes and explores the decoding algorithm of Turbo-Code, compares several kinds of decoding algorithms and produces the functional characteristic curves by using Matlab simulation. According to the characteristics of code structure and iteration decoding of Turbo- Code, Log-MAP algorithm is improved.
