摘要
在研究了针对极化码而提出的连续删除列表译码原理的基础上,探讨了在常用数字调制下极化码译码性能。通过Matlab完成多种调制系统下的仿真,并对它们进行比较、分析,以便理解其优缺点及适用场合,实验结果表明,上述调制方式以较低的代价在不同程度上改进了极化码的译码性能,为后续的应用研究提供参考。
The list decoding theory of Polar Codes is studied and then the performance in commonly used modulation mode is explored. The simulations are made by Matlab to compare and analyze the difference of different modulation systems in order to understanding the merits and demerits and their applications. The experimental results show that the modulation modes improve the Polar code decoding performance at a relatively low cost and then provide reference for subsequent application.
