Method and system for sending information over metal wire

摘要

In a system and method of transmitting information over metal wire, a plurality of base band encoded frequencies are combined to create a single complex, modulated signal that will produce a desired throughput. The various digital signals are encoded using phase shifting to represent logic changes. At the receiver, the signals are separated and each signal is decoded by considering several sidebands for each baseband signal, covering 180° of phase. Synchronicity is ensured by transmitting a pilot frequency.
