论文摘要
我们提出了用于极地代码的非均匀量化解码器。量化器的设计指标是最大程度地减少量化产生的失真。量化器是通过动态编程获得的，并且也证明了量化器的最优性。仿真结果表明，与传统的浮点线解码器相比，所提出的非均匀量化解码器的误差校正性能降解小于0.1 dB，在5位非均匀量化下，误差量化量降解，比以前的均匀量化解码器对极性代码明显优于先前的均匀量化解码器。
We propose a nonuniform quantized decoder for polar codes. The design metric of the quantizers is to minimize the distortion incurred by quantization. The quantizers are obtained via dynamic programming and the optimality of the quantizer is proved as well. Simulation results show that the error correction performance degradation of the proposed nonuniform quantized decoder is less than 0.1 dB compared to conventional float-point decoders under 5-bit nonuniform quantization, outperforming previous uniform quantized decoders for polar codes significantly.
