What are the advantages of phase shift keying (PSK)?


Quick Answer

The main advantage of phase shift keying is that it allows data to be carried along a radio communications signal much more efficiently than with frequent shift keying. PSK is a digital modulation scheme that transports data by changing the phase of the carrier wave.
