摘要
Abstract
Recently,Polar codes are seen as a breakthrough in channel coding.It has been proved that they can achieve the Shannon Limit under discrete memoryless channels. Moreover,their encoding and decoding algorithm have low complexity. The SCL decoding algorithm is an improved version of SC algorithm,which bridges the gap between the SC and the ML decoding of polar codes. Based on this algorithm,a SCL polar decoder with code length N=1024 and the list width L=32 is proposed,5SGX-EA7N2F45C1 chip of Altera Stratix V series are chosen to implement. The final results show that the decoder can achieve the throughput of about 6.5Mpbs under operating frequency of 300MHz.关键词
