Research on Impulse Noise Suppression Method of Power Line Communication Based on Cross-correlation

Impulse noise have an important influence on the communication quality of low voltage power lines. Based on the actual noise of industrial scene, the time-domain characteristics of typical impulse noise and the cross-correlation between three-phase noise are analyzed, and an impulse noise suppression method based on adaptive filtering algorithms is proposed. The performance is verified by building a bit error rate simulation platform of power line communication based on QPSK modulation. The results show that the impulse noise suppression method based on LMS and NLMS algorithms has significant improvement effect on bit error rate.
