摘要
基于硬件资源有限的低轨卫星通信环境,以极化码作为信道编码方式,将循环冗余校验(CRC)辅助连续取消列表(SCL)译码器(CRC aided SCL,CA-SCL)结合关键集以及自适应算法,提出一种优化的CA-SCL译码器(optimized CA-SCL,OCASCL),该译码器的译码性能优于经典CA-SCL译码器,运算复杂度可降低65%~70%。
Based on the low-orbit satellite communication environment with limited hardware resources,this paper uses polarization code as the channel coding method,and combines the successive redundancy check(CRC)assisted successive cancellation list(SCL)decoder(CA-SCL)with critical sets and adaptive algorithms to propose an optimized CA-SCL decoder(OCASCL).The performance of the OCASCL decoder is better than the classic SCL decoder,the computational complexity can be reduced by 65%-70%.
