提出了一种针对给定列表大小的连续消除列表(SCL)译码的极化码启发式构造方法,以平衡在误帧率(FER)衡量的性能和解码复杂度之间的权衡。此外,还提出了一种基于动态冻结比特且在“低权重比特”(LWB)之间存在约束的构造方法。仿真结果表明,在SCL译码下,LWB - 极化码的性能优于CRC - 极化码和eBCH - 极化码。
A heuristic construction of polar codes for successive cancellation list (SCL) decoding with a given list size is proposed to balance the trade-off between performance measured in frame error rate (FER) and decoding complexity. Furthermore, a construction based on dynamically frozen bits with constraints among the "low weight bits" (LWB) is presented. Simulation results show that the LWB-polar codes outperform the CRC-polar codes and the eBCH-polar codes under SCL decoding.
