电力线信道中极化码译码算法的改进OACSTPCD

Pulse noise is the most primary factor that affects the performance of power line communication.In order to enhance the performance of polar codes in power line channels,this paper proposes a segmented CA-SCL bit-flipping decoding algorithm and makes simulations in both additive white gaussian noise and power line channels.In constructing the critical set,the algorithm introduces Rate1 sub-block to avoid the complexity of searching the entire set,and segmentation are conducted based on the positions of the bits in the critical set,and each segment flips one bit,achieving multi-bit flipping.Simulation results show that the performance of the SCA-SCL-BF algorithm outperforms that of existing literature significantly when signal-to-noise ratios>0dB.The algorithm has a great significance in improving power line transmission.
