Segmented CRC Aided SC List Polar Decoding
Because of the existence of channel noise, channel coding serves as an indispensable part of mobile communication system and the essential guarantee for the reliable, accurate, and effective transmission of information. As one of the most competitive channel code candidates for the 5th generation (5G) mobile communication, polar codes are the first codes which can provably achieve the symmetric capacity of binary input discrete memoryless channels (B DMCs) In this paper, the segmented CRC aided successive cancellation list (SCA SCL) polar decoding scheme is proposed for better tradeoff of performance and complexity. Numerical results on binary input additive white Gaussian noise channel (BI AWGNC) have shown that, at SNR of 0.5 dB, this approach successfully provides as high as 41.65% complexity reduction and similar decoding performance compared to state of the art ones.
