Abstract
Power frequency communication is a new type of data transmission system with the medium of distribution power network. Detection of the inbound signal is easily influenced by 50 Hz fundamental wave and its 5th harmonic currents. The counteracted current by going through the notch filter based on adaptive filter technique is proposed to eliminate the residual fundamental wave and its harmonic wave. And the practice proved that when the matched filter is further adopted, power frequency communication system can be adjusted to the power network environment in the high energy consuming area with the good performance of detecting the inbound signal.
