一种基于循环冗余校验的极化码自适应逐次消去列表译码器

An Adaptive Successive Cancellation List Decoder for Polar Codes with Cyclic Redundancy Check

Bin Li, Hui Shen, David Tse

摘要:

在这封信中,我们提出了一个自适应SC(连续取消)列表解码器的极性码与CRC。这种自适应SC列表解码器迭代地增加列表大小,直到解码器输出包含至少一个可以通过CRC的生存路径。仿真结果表明,自适应SC列表解码器提供了显着的复杂度降低。我们还证明了由我们提出的具有非常大的列表大小的自适应SC列表解码器解码的具有24比特CRC的极化码(2048,1024)可以在Eb/No=1.1dB处实现帧出错率FER=0.001,这与在该块长度处的信息理论极限相差约0.2dB。

英文摘要:

In this letter, we propose an adaptive SC (Successive Cancellation)-List decoder for polar codes with CRC. This adaptive SC-List decoder iteratively increases the list size until the decoder outputs contain at least one survival path which can pass CRC. Simulation shows that the adaptive SC-List decoder provides significant complexity reduction. We also demonstrate that polar code (2048, 1024) with 24-bit CRC decoded by our proposed adaptive SC-List decoder with very large list size can achieve a frame error rate FER=0.001 at Eb/No=1.1dB, which is about 0.2dB from the information theoretic limit at this block length.
