DIGITAL WIRELESS PHONE/MODEM JACK CAPABLE OF COMMUNICATIONS OVER THE POWER LINES USING DIFFERENTIAL BINARY PHASE SHIFT KEYING (DBPSK)

摘要

A system for communication signals between a transmitter and a receiver using digital modulation techniques is provided. In one preferred embodiment of this invention a modulator is a differential binary shift key modulation. The modulator comprises a digitizer (101), a summer (102), a differential encoder (103), and a phase shifter (104).
