摘要：

Dear editor,Polar codes [1] provably achieve the capacity of binary-input memoryless channels under successive cancellation (SC) decoder. Cyclic redundancy check (CRC) aided successive cancellation list (CA-SCL) decoder [2] is an enhanced version of SC decoder and its block error rate (BLER) is comparable to the state-of-art low-density parity check code. However, the complexity of SCL algorithm grows linearly with list size L. When decoding polar codes with large L, the decoding latency can hardly meet stringent latency demand in next generation wireless networks. Hence, reducing the latency of SCL decoder is an important issue.
