Performance Analysis of Joint Source-Channel Decoding Based on MS Estimation and Iterative Structure
基于MS估计和迭代结构的信源信道联合解码系统性能分析

Based on structure of MS estimation soft-bit source decoding and iterative source-controlled channel decoding, this paper deduces the parameter SNR and BER upper bound for above joint source-channel decoding respectively, and gives the factors which determine the improvement of system performance. The result shows the feasibility of joint source-channel decoding algorithm. Also, simulation proves the validity of analysis process.
