极化码多模串行抵消算法的FPGA实现研究

Study on implementation of multi-mode successive cancellation algorithm for polar decoder in FPGA

文章根据极化码的编码结构,提出了一种递推的串行抵消译码策略。利用该策略可以将长极化码译码器改造为支持任意低于该码长的极化码译码,从而降低支持多种服务模式应用的硬件资源开销。

A recursive successive cancellation decoding strategy for polar codes based on its implicit structure is proposed in this paper. Using this strategy, the long-length polar decoder can be transformed to support any polarization code decoding below the code length, thereby reducing the hardware resource overhead that supports multiple service mode applications.
