摘要

Dear editor, Polar codes can achieve the symmetric capacity of binary-input memoryless channels with infinite code length under successive cancellation (SC) decoding [1].Cyclic redundancy check (CRC) aids in successive cancellation list (CA-SCL) [2,3] and a decoder is proposed to improve the finite length performance of polar codes.To achieve the spectrum efficiency required by next generation wireless networks,it is essential to combine polar codes with higher order modulation.
