二进制对称信道和擦除信道下Reed-Solomon码的代数软译码性能分析

Performance Analysis of Algebraic Soft Decoding of Reed-Solomon Codes over Binary Symmetric and Erasure Channels

Jing Jiang, Krishna R. Narayanan

摘要:

本文研究了RS码在擦除信道和二进制对称信道下的代数软译码的译码域。最佳多重数分配策略(MAS)的调查和紧界推导出ASD可以显着优于传统的Berlekamp Massey(BM)解码在这些信道的一个很宽的码率范围。该分析技术还可以扩展到其他信道模型,例如,擦除信道上的RS编码调制。

英文摘要:

In this paper, we characterize the decoding region of algebraic soft decoding (ASD) of Reed-Solomon (RS) codes over erasure channels and binary symmetric channel (BSC). Optimal multiplicity assignment strategies (MAS) are investigated and tight bounds are derived to show the ASD can significantly outperform conventional Berlekamp Massey (BM) decoding over these channels for a wide code rate range. The analysis technique can also be extended to other channel models, e.g., RS coded modulation over erasure channels.
