极化码研究综述

A survey of polar code research

信道编码(纠错编码)是可靠通信的基础。极化码是第一种被理论证明可以达到信道容量的信道编码方法,具有可实用的线性编译码复杂度以及优良的检纠错性能。得益于极化码在复杂度与性能方面的独特优势,极化码在新一代移动通信、卫星通信、深空探测等领域具有广阔的应用前景。近年来,随着极化码被正式应用于第五代移动通信标准,极化码的理论与应用研究取得了日新月异的进展。结合所在团队的研究,针对极化码研究中的几个热点问题,对极化码研究现状进行了综述与总结,并对极化码未来的研究进行了展望。

Channel coding(error correction coding)is the basis of ensuring the reliable communication.Polar code is the first constructive coding method which can achieve the channel capacity.It has practical linear encoding and decoding complexity and excellent error correction and detection performance.The unique advantages of polar codes make it have a broad application prospect in the communication systems such as next-generation mobile communication systems,satellite communications,deep space exploration.In recent years,with the application of polar codes in the fifth-generation mobile communication standards and systems,the theory and application of polar codes are changing with each passing day.In this paper,several hot issues in the research of polar codes are summarized,and the future research of polar codes are discussed.
