Summary:This invention relates generally to a power line communication system and more particularly, to a power line communication system for communicating commands and data on a power line. A communication system for communicating a modified geometric harmonic modulated (GHM) signal on a power line is described. The system includes a transmitter for transmitting a GHM signal having a plurality of carriers, a highest frequency carrier being about 630 Hz, and a receiver for receiving the transmitted GHM signal.
