M-ary phase shift keying

WebWe show for the first time, to the best of our knowledge, that, in a coherent communication system that employs a phase-shift-keying signal and Raman amplification, besides the pump relative intensity noise (RIN) transfer to the amplitude, the signal’s phase will also be affected by pump RIN through the pump–signal cross-phase … WebM-ary PSK Modulation What is the M-ary PSK Modulation? M-ary Phase Shift Keying - or MPSK - is a modulation where data bits select one of M phase shifted versions of the carrier to transmit the data. Thus, the M possible waveforms all have the same amplitude and frequency but different phases. The signal constellations consist of M equally spaced …
