基于FCNN的极化码分区译码算法研究
Research on polar code partition decoding algorithm based on FCNN
摘要
Abstract
To reduce the dimensionality constraints of neural network decoders for polar codes during the training phase,a parti-tioned successive cancellation(SC)decoder based on fully connected neural networks(FCNN)is designed.By dividing the polar code decoding tree into two regions and processing each with differently parameterized FCNNs,the need for large-scale training data is reduced.The simulation results show that in an additive white Gaussian noise(AWGN)channel,when the signal-to-noise ratio(SNR)is between 1 to 5 dB,the performance of the FCNN-SC decoder approaches that of the SC decoding algorithm.When the SNR is between 1.5 to 3 dB,the FCNN-SC decoder achieves approximately 0.5 dB coding gain compared to the FCNN de-coder,and requires a smaller dataset during the training phase,being roughly half the size needed for the FCNN decoder.关键词
