| 为解决5G场景下的极化码编码设计问题，本文通过对两种符合5G保准规定的控制上下行信道最大编码长度的极化码进行Matlab仿真测试，研究了5G场景的极化码编码的最佳设计方案。首先将输入序列根据上下信道分别对应的CRC生成多项式，添加CRC比特。然后采用巴氏参数法进行极化信道可靠性估计，在可靠性高的信道传送信息序列。最后对不同的编码结构进行仿真，对仿真结果进行性能分析。结果表明：不实施比特反转的生成矩阵的编码方法的编码效率最高、用时最短。 |

| In order to solve the problem of polar code coding design in 5G scene, this paper studies the optimal design of polarization code coding in 5g scene. Two kinds of polar codes which accord with 5G standard are used for MATLAB simulation test. Firstly, according to the CRC corresponding to the upper and lower channels, the input sequence generates polynomials. Then, the reliability estimation of polarization channel is carried out by using pap parameter method. High reliability of the channel is used to transmit information sequence. Finally, simulation of different coding structures and performance analysis of simulation results. The results show that the encoding method without bit inversion has the highest encoding efficiency and the shortest encoding time. |
