Power Line Home Network Design Based on OFDM Technology

Jian Zhang

Abstract

The transmission characteristics of power line channel were introduced,and the power line communication system was analyzed from the field of home network.The concrete scheme of home network based on the transmission medium of power line was given out.The methods of constructing the intelligent home network based on the OFDM technology,the system model and the hardware realization methods of power line communication system based on the DSP chip were given.Combining the latest OFDM technology,the channel coding technology and the modulation and demodulation technology in the power line communication system were researched,and the simulaion results of system design was given.
