Introduction - If you have any usage issues, please Google them yourself
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
