摘　　要：极化码凭借其出色的性能成为了未来6G实现超可靠低时延通信最具潜力的候选信道编码方案之一。基于对极化码、PAC码重量分布的定量分析,探究了RM-Polar构造和预编码过程能够提升极化码可靠性的原理。在此基础上,通过替换部分特定的信息信道,进一步提升了极化码的性能。仿真结果表明,优化后(256,128)极化码和PAC码的错误系数显著降低,在10-5的误分组率条件下,分别带来了约0.28 dB和0.53 dB的额外编码增益。Due to their exceptional performance,polar codes have become one of the most promising candidate channel coding schemes for achieving ultra-reliable low-latency communication in future 6G networks.This paper presents a quantitative analysis of the weight distribution in polar and PAC codes,exploring how RM-Polar construction and precoding processes can enhance the reliability of polar codes.Building on this analysis,we further improve the performance of polar codes by replacing certain specific information channels.Simulation results show that the optimized(256,128)polar codes and PAC codes achieve significant reductions in error coefficients,providing additional coding gains of approximately 0.28 dB and 0.53 dB,respectively,at a block error rate of 10-5.
