摘要/Abstract

摘要：

极化码作为 3GPP 标准制定中的一种信道编码技术方案，具有良好的纠错性能。为了进一步提高删余极化码的误码率性能，将极化码中基于位反转置换的缩短算法应用到系统极化码，提出一种系统极化码的缩短方法。仿真结果表明，在AWGN信道中，在高码率条件下，建议的系统极化码的缩短方法的误码率性能优于系统极化码的准均匀凿孔方法，也优于极化码的缩短方法。当码率为3/4、误码率为10^-4时，系统极化码的缩短方法比极化码的缩短方法约有0.5 dB的增益，比系统极化码的准均匀凿孔方法约有0.25 dB的增益。

关键词: 系统极化码, 位反转置换, 缩短

Abstract:

Polar code,as a channel coding scheme in 3GPP standard,has good error correction performance.In order to further improve performance of the BER of the punctured Polar code,the shortening algorithm based on bit-reverse permuation was applied to the system Polar code,and a shortened system polar code was proposed.Simulation results show that in the AWGN channel,under the condition of high code rate,the performance of the BER of the proposed method is better than both the punctured system Polar code and the shortened Polar code.When the code rate is 3/4 and the BER is 10^-4,the proposed method can obtain a gain of about 0.5 dB than the shortened Polar code,and a gain of about 0.25 dB than the punctured system Polar code.

Key words: system Polar code, bit-reverse permutation, shortening
