摘　　要：针对低轨卫星通信中块衰落信道,提出了改进的极化重量Polar码构造算法。仿真对比了Polar码和CCSDS建议的LDPC码在块衰落信道下的性能。结果表明,在中等码长和码率的情况下,将Polar码应用于低轨卫星通信中能够获得一定的性能增益,且其编译码复杂度较低。For block fading channel in LEO satellite communication,this paper proposed an improved polarization weight Polar codes construction algorithm with simulation and comparison about the performance of Polar codes and LDPC codes recommended by CCSDS under block fading channel.The results show that in the case of medium code length and rate,applying Polar codes to LEO satellite communication can achieve performance gains,with low complexity of coding and decoding.
