Joint Soft Iterative Decoding Algorithm Based on MSK and LT Codes
Pages: 126-129
Year: Issue:  1
Journal: Video Engineering

Keyword:  LT码软译码MSKSISO算法联合软迭代;
Abstract: 传统的简单级联编码调制系统在译码时会造成软信息损失.提出了一种基于MSK和LT码的联合软迭代译码算法,设计了算法的系统模型.利用LT码的软译码和MSK调制的SISO算法,进行联合软迭代译码,提高了编码调制系统的性能.仿真结果表明:在误码率为10-4时,提出的算法比传统的简单级联编码调制算法约有1.5 dB的编码增益.
