Abstract

Large-amplitude random impulsive noise and harmonic noise have a very serious impact on the quality of low-voltage power line communication. Taking the time-domain sparsity of random impulsive noise and the frequency-domain sparsity of harmonic noise into consideration, we apply Compressive Sensing (CS) theory to reconstruct the noise, and to restrict the power line noise. The simulations show that the orthogonal matching pursuit (OMP) algorithm can effectively reconstruct the random impulse noise and harmonic noise. Applying this method to the research of carrier communication module interchangeability,we can reduce the bit error rate caused by carrier module interchange, and improve the robustness of carrier communication system.
