极化码的置信传播列表有序统计译码

Belief Propagation List Ordered Statistics Decoding of Polar Codes

Guy Mogilevsky, David Burshtein

摘要:

示出了如何将极性码的有序统计解码(OSD)与CRC辅助的置信传播列表(CBPL)解码相结合。即使当OSD的再处理顺序低至1时,新的解码器被示出为显着改善CBPL。对于高于一个的再处理顺序,我们建议部分再处理,其中只考虑与最不可靠的部分的置信传播解码最可靠的独立位相关联的错误模式。这种类型的部分再处理提供了性能和计算复杂性之间的折衷。

英文摘要:

It is shown how to combine ordered statistics decoding (OSD) with CRC-aided belief propagation list (CBPL) decoding of polar codes. Even when the reprocessing order of the OSD is as low as one, the new decoder is shown to significantly improve on CBPL. For reprocessing orders higher than one, we suggest partial reprocessing, where only error patterns associated with the least reliable part of the belief propagation decoded most reliable independent bits are considered. This type of partial reprocessing offers a trade-off between performance and computational complexity.
