摘要
Abstract
LDPC codes has broad application prospects in satellite navigation and communication under poor channel conditions, but while the ground receiving terminal with BP or MP and other soft-decision decoding algorithm has good performance, its large computing amount is not conducive to receiver miniaturization and cost reduction. In this paper, based on bit flipping hard decision decoding algorithm, several improved hard-decision decoding algorithms are proposed, and their decoding performance comparison is provided under a shorter code length. Simulation results show that ： under the short code length conditions,the improved hard - decision decoding algorithm MWBF and RRMWBF have good decoding performance to meet the short - message communication requirements of Compass Ⅱ.关键词
