中文摘要：

极化码目前是5G通信技术中的信道编码之一。串行抵消列表译码算法是极化码中最受欢迎的译码算法之一。尽管现有的列表译码算法已经得到优化,但是算法中存在数据相同且未被更新的存储空间,造成存储空间的不必要开销,也增加了计算量。论文在原有算法的基础上对算法进行优化,有效节省存储空间,仿真表明,计算量也得到一定的降低。

英文摘要：

Polar codes are currently one of the candidate channel The list decoding algorithm is one of the most popular decoding codes in 5G communication technology. algorithms for polar codes. Although the existing list decoding algorithm has been optimized, some storage space has been updated once or never visited, which results in unnecessary overhead storage space and the increasing the amount of computation. In this paper, the optimization is done based on the original algorithm for saving storage space, and the simulation results show that the amount of calculation is reduced.
