摘要/Abstract

摘要：

信道编码方案中的极化码是5G通信领域中的研究热点。极化码在串行抵消译码下容易受到差错传播的影响，在中短码长上的性能并不理想。针对这些问题，在不同仿真情况下对系统极化码和非系统极化码的性能差异性进行了研究。仿真结果表明，系统极化码比非系统极化码具有更好的误码率性能；相比非系统极化码，系统极化码在串行抵消译码下对差错传播具有较强的抵抗性。上述结果对极化码性能的优化以及5G通信有重要的理论价值。

关键词: 性能比较, 系统极化码, 误码率, 串行抵消译码

Abstract:

Polar code in channel coding schemes is a research hotspot in 5G communication field.Polar code is susceptible to error propagation under successive cancellation decoding,and the performance of the code at short and medium block lengths is not ideal.For the problems,the performance difference between systematic polar code and non-systematic polar code was studied under various simulation conditions.Simulation results demonstrate that systematic polar code has advantage over non-systematic polar code in bit error rate performance,and the former are more robust against error propagation than the latter under successive cancellation decoding.The above results are considerable importance from the theoretical values in 5G communication and performance optimization of polar code.

Key words: performance comparison, systematic polar code, bit error rate, successive cancellation decoding
