摘要

分集接收技术是瑞利衰落信道中抗衰落最有效的办法之一，为了改善Polar码在瑞利衰落信道中的性能，提出了一种基于Polar码的分集接收系统。分析了Polar码在瑞利衰落信道中的构造方式，确定了分集接收系统中Polar码的信息位选择序列，并推导出了Polar码在分集接收系统中误码率的理论上界。仿真结果表明，当采用四重分集时，Polar码能获得3 dB的编码增益，相比LDPC码有0.6 dB的性能优势；当采用八重分集时，Polar码能获得5 dB的编码增益，相比LDPC码有1.5 dB的性能优势。分集接收能够显著提升Polar码在瑞利信道中的编码性能。

Abstract

Diversity reception is one of the most effective ways to resist fading over Rayleigh fading channels

in order to improve the performance of Polar codes over Rayleigh fading channels

a diversity reception system based on Polar code was proposed.The information bit selectionsequences of Polar codes in diversity reception were determined

and the upper bound of BER for Polar codes in diversity reception system was derived.The simulation results show that when quadruple diversity reception is used

the encoding gain is greater than 3 dB and has 0.6 dB performance advantage compared to LDPC code.Experiment results show that

when eightfold diversity is used

the encoding gain is greater than 5 dB and has 1.5 dB performance advantage compared to LDPC code

and diversity reception can significantly improve the performance of the system.
