METHOD AND APPARATUS FOR MULTI-LEVEL PHASE SHIFT KEYING COMMUNICATIONS

摘要

Methods and apparatus for detecting multiple-level phase shift keying (MPSK) signals based on detectors that have nonlinear dynamics transfer characteristics are disclosed. The receiver circuit can be implemented easily using devices such as the op-amps to provide the required dynamic characteristics. The performance is enhanced by transmitting multiple cycles of the PSK signals and gating of the received waveforms.
