短码长纠错码的性能比较

Performance Comparison of Short-Length Error-Correcting Codes

J. Van Wonterghem, A. Alloum, J. J. Boutros, M. Moeneclaey

摘要:

我们比较了短长度线性二进制码在二进制擦除信道和二进制输入高斯信道上的性能。我们使用一个通用的解码器,可以解码任何线性二进制分组码:高斯消除基于最大似然解码器的擦除信道和高斯信道上的概率有序统计解码器。因此,我们比较代码而不是解码器。对于长度为256比特的LDPC、Reed-Muller、Polar和BCH码,找到字出错率与信道参数的关系。在没有循环冗余校验的情况下,BCH码优于其他码。在联合译码下,循环冗余校验的级联使得所有码的性能非常接近最优下界。

英文摘要:

We compare the performance of short-length linear binary codes on the binary erasure channel and the binary-input Gaussian channel. We use a universal decoder that can decode any linear binary block code: Gaussian-elimination based Maximum-Likelihood decoder on the erasure channel and probabilistic Ordered Statistics Decoder on the Gaussian channel. As such we compare codes and not decoders. The word error rate versus the channel parameter is found for LDPC, Reed-Muller, Polar, and BCH codes at length 256 bits. BCH codes outperform other codes in absence of cyclic redundancy check. Under joint decoding, the concatenation of a cyclic redundancy check makes all codes perform very close to optimal lower bounds.
