Abstract
A transmitter transmits an outbound message signal via the power distribution system. The transmitter includes a spreader for spreading the spectrum of the communications signal before transmitting the outbound message signal. A receiver despreads the spectrum of the received digitized signal and digitally demodulates the received despread signal to generate the message. The transmitted signal is orthogonal to a source of interference on the power distribution system.
