A spread spectrum modem for use on electrical power lines

University of British Columbia

The design, implementation, and testing of a spread spectrum modem for use on electrical power lines are described in this thesis. It is shown that for data communication over power lines, spread spectrum signalling has performance advantages over signalling formats which use a narrow frequency band. Synchronization for the modem is based on the 60 Hz power line signal and significantly reduces the complexity of the modem. A spread spectrum transmitter and receiver are implemented and performance results on some representative power line circuits are presented. The modem performed well and appears to be a viable candidate for data communications over power lines.
