Parallel concatenated systematic polar code based on soft successive cancellation list decoding
Zhenzhen Liu, Kai Niu, Jiaru Lin · 2017
In this paper, we investigate the parallel concatenated systematic polar code (PCSPC) with soft successive cancellation list (SSCL) decoding algorithm. Based on the successive cancellation list (SCL) decoding, the key process of SSCL about how to calculate the soft information which is need for the iterative decoding is presented in detail. Compared to PCSPC with belief propagation (BP) decoding or soft cancellation (SCAN) decoding, the one with SSCL decoding has about 0.6 or 0.5 dB performance gains at bit error rate 10-4.
