Encoder and list decoder of Reed Solomon kernel based polar codes
In this paper, we propose the encoding and list decoding method of polar codes based on the four dimensional Reed Solomon (RS 4) kernel. In specific, an encoding table based method is employed to reduce the computational complexity of both encoder and decoder. In addition, a simplified method to update log likelihood ratios (LLRs) which employs additions instead of exponential calculations is also proposed to further increase the decoding speed. In addition, we present a method to construct RS 4 polar codes using genie aided simulations, where the symbol channel capacity is determined by the number of decoding errors. Through simulations, we show the decoding performance of the RS 4 polar codes and compare it with the binary polar codes.
