Description: Phase shift keying (PSK) is a large class of digital modulation schemes. PSK is
widely used in the communication industry. In this chapter we study each PSK modulation
scheme in a single section where signal description, power spectral density,
modulator/demodulator block diagrams, and receiver error performance are all included.
First we present coherent binary PSK (BPSK) and its noncoherent counterpart,
differential BPSK (DBPSK), in Sections 4.1 and 4.2. Then we discuss in
Section 4.3 M-ary PSK (MPSK) and its PSD in Section 4.4. The noncoherent
