摘要

本文给出了考虑瑞利衰落信道传输的调制分集与极化码结合使用的初步结果。其主要思想是通过在传统的极化编码方案中加入分集来提高通信系统的性能。仿真结果表明，在所有码长的情况下，该系统的性能都优于原系统。例如，在考虑码长N=1024和误码概率为10^-3的情况下，所提出的系统可以获得8 dB的信噪比增益。

Performance of Modulation Diversity with Polar Encoding in Rayleigh Fading Channel

This paper presents preliminary results concerning the use of modulation diversity combined with polar codes considering the transmission over Rayleigh fading channel. The main idea is to improve the performance of the communication system by adding diversity in a conventional polar coding scheme. Simulations results show that the proposed system outperforms the original one for all code lengths. For instance, gains of 8 dB in terms of the signal-to-noise ratio can be obtained with the proposed system considering a code length of N=1024 and a bit error probability of 10^-3.
