摘要
极化码是一种新的编码技术，是第一种能达到香农极限的构造码，具有较低的编译码复杂度，且当码长很长时误码率可以非常小。本文主要研究了极化码sc译码算法，根据译码原理给出了译码的结构，并探讨了译码所需的指数项的计算方法，根据译码算法设计出了译码流程，并在文章最后给出了指数项之间的关系结构图。
Polar code is a new coding technique, and is the first construction code to reach Shannon limit. The complexity of encoding and decoding is lower and the error rate can be very small when the code length is longer. This paper principally studies the SC decoding algorithm for polar code, and gives the decoding structure according to decoding principle, and then discusses the computation method of index required for decoding. The decoding process is designed based on decoding algorithm, and finally the structure diagram to indicate the relationship between index terms is given.
