Phase-shift keying (PSK) is a modulation process whereby the input signal, a binary PCM waveform, shifts the phase of the output waveform to one of a fixed number of states. The demodulation process can be divided into three major subsections, as shown by Figure 4. First, since the incoming waveform is suppressed carrier in nature, coherent detection is required. The methods by which a phase-coherent carrier is derived from the incoming signal are termed, carrier recovery, and will be covered first.

说明：  Today’s wireless networks are characterized by a fi xed spectrum assignment policy. However, a large portion of the assigned spectrum is used sporadically and geographical variations in the utilization of assigned spectrum ranges from 15 to 85 with a high variance in time. The limited available spectrum and the ineffi ciency in the spectrum usage neces- sitate a new communication paradigm to exploit the existing wireless spectrum opportunistically
