The simulation of powerline communication based on OFDM technology using MATLAB

This paper describes a powerline communication system based on OFDM technology,and presents the result of the system simulation in PC.When OFDM technology is employed in the powerline communication,the important problem,such as power peak to mean ratio,synchronization and interference,are discussed in the paper.The result of the system simulation in PC reveals that there are several advantages of OFDM technology as compared to traditional single carrier or spectrum systems,which are higher bandwidth efficiency and more robust against frequency selective attenuation etc.,and therefore OFDM technology would been adopted as high speed communication in the powerline.
