Method and apparatus for three-phase power line communications

摘要

Method and apparatus for generating a balanced three-phase power line communication signal. In one embodiment, the method comprises generating a plurality of modulation signals based on at least one data stream; modulating a plurality of carrier signals by the plurality of modulation signals to generate a balanced three-phase PLC signal comprising a first phase signal, a second phase signal, and a third phase signal; and coupling the balanced three-phase PLC signal to a three-phase power line.

1. A method for generating a power line communication (PLC) signal, comprising:
generating a first modulation signal based on at least one data stream; modulating a first carrier signal by the first modulation signal to generate a first signal; generating a second signal by performing a phase shift via a lookup table based on the first signal; and coupling a balanced three-phase PLC signal comprising the first signal, the second signal and a third signal to a three-phase power line.
