一种基于CRC-SCL的极化码译码算法
A CRC-SCL based Decoding Algorithm of Polar Codes
摘要
Abstract
Polar codes is a type of error-correction codes, which can reach the Shannon limit.Through years of study, many high-performance decoding algorithms have been proposed.Based on the traditional successive cancellation decoding algorithm, we study the principles and structure of the algorithm.In order to improve the performance of polar codes, we propose CRC-SCL and lazy copy algorithms to reduce the complexity of the algorithm.The simulation results show that compared with the SC algorithm, the SCL algorithm can significantly improve decoding performance with lower complexity.关键词
