基于CRC的Polar-LDPC级联的优化方案

Optimal scheme of polar-LDPC cascade based on CRC

作为5G通信标准中信道编码方案的极化码和LDPC码,极化码作为新兴的信道编码方案,极化码的技术尚不成熟,为适应2020年5G网络的商用化,本文分析CRC对Polar-LDPC级联方案的性能影响,并模拟AWGN信道,对提出的两种基于CRC优化的级联方案进行仿真,仿真显示,基于CRC的级联方案,相较于原级联方案,分别提升了0.2~0.3dB。

As a channel coding scheme in 5G communication standard: polarization code and LDPC code, polar code as a new channel coding scheme, the technology of polarization code is not yet mature. In order to adapt to the commercialization of 5G network in 2020, this paper analyses the impact of CRC on the performance of Polar-LDPC cascade scheme, and simulates AWGN channel. The simulation results show that the proposed two cascade schemes based on CRC optimization are simulated. Compared with the original cascade scheme, the cascade scheme based on CRC has increased by 0.2~0.3 dB.
