APPARATUS AND METHOD FOR IMPLEMENTING DIGITAL COMMUNICATIONS ON A POWER LINE.

摘要

An apparatus to establish bi-directional digital communication over a power line network includes a signal launching circuit (305T) to impose a digital communication signal onto a power signal carried by a power line network. The signal launching circuit is configured to position a pulse of the digital communication signal at any phase location of each half cycle of the power signal. A receiver (306) leads the digital communication power signal at a second point in the power line network. A signal processor (604) is connected to the receiver to recover the digital communication signal from the digital communication power signal.
