Abstract
The invention provides a layered modulation data communication systems characterized by numerous, asynchronous data transmitters operating on a power line. Data is modulated onto relatively low frequency subcarriers. Subcarriers are used to modulate carriers centered on a common frequency. The subcarriers are frequency division multiplexed. Data is recovered by demodulating the subcarriers from the carriers and subsequently demodulating the data from the subcarriers.
