摘要：
In this paper, we propose a simplified multi-bit successive cancellation list (SMSCL) decoding method for polar codes. In the proposed SMSCL decoding, frozen bits are ignored, and multiple information bits are intermediately decoded at each decision step. In addition, a modified two-stage pruning network is proposed to reduce the complexity of path pruning in SMSCL decoding. Compared to the existing multi-bit SCL decoders, the SMSCL decoder can achieve significant latency and complexity reduction over a wide range of code rates.
