基于重量分布的高性能极化编码构造研究
High-Performance Polar Code Construction Based on Weight Distribution
摘要
Abstract
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.关键词
