Application of Spectrum-spread Technology in Power Line Communication

摘要

In this paper, on the basis of the analysis of power line channel characteristic,we firstly build a power line channel mode. And then, we elaborate the spectrum theory and its main performance indexes. At last, the direct sequence spread spectrum communication system is build by MATLAB/Simulink using the power line channel mode. The simulation results prove that the Spectrum-spread Technology can be used in Power Line Communication.
