数字调制技术是现代通信领域的一个重要环节,对于远距离通信中的噪声累加问题,可以通过脉冲判决再生的方式来消除,因此有效的调制方式对于提高频带利用率以及信号传输的可靠性有着非常重要的意义。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 analyze of polar code decoding performance in digital modulation modes

Digital modulation technology is an important part in the field of modern communications, the digital modulation can avoid the accumulation of the noise in telecommunication by judgement regeneration of pulses and so the effective ways of modulation have very important significance in raising the utilization ratio of frequency band and the reliability of signal transmission. The paper studied the list decoding theory of Polar Codes and then explore the performance in commonly used modulation mode. We made the simulations 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 improved the Polar code decoding performance at a relatively low cost and then provide reference for subsequent application.
