Research on Denoising Methods in Power Line Communication
PROCEEDINGS OF THE INTERNATIONAL CONFERENCE ON LOGISTICS, ENGINEERING, MANAGEMENT AND COMPUTER SCIENCE (LEMCS 2015)(2015)
摘要
With the development of power line communication (PLC) technology, it is widely used in smart grid. In this paper, we mainly introduce communication modes of PLC, and respectively analysis their advantages and disadvantages. Moreover channel noises are described in the paper, and we respectively simulate background and impulsive noise in modeling. Finally we introduce compressed sensing and Sparse Bayesian Learning denoising methods. Using MATLAB to simulate them, we analyze the simulation result and compare their signal to noise ratio (SNR).
