Abstract
A receiver for decoding passband signal pulses transmitted in accordance with a M-ARY phase shift keying modulation scheme, comprises a multiphase sampler for sampling received passband signal pulses in the passband frequency range so as to generate a plurality of digital words corresponding to the sampled passband signal pulses, such that each digital word represents the phase of each sampled passband signal pulse. A phase reference register or other storage device is coupled to the multiphase sampler for storing one of the digital words as a phase reference such that other digital words generated by the multiphase sampler are compared with the digital word corresponding to the phase reference for decoding the passband signal pulses.
