DIGITAL MODULATION TECHNIQUES the material describes digital modulation techniques such as BINARY PHASE SHIFT KEYING (BPSK), DIFFERENTIAL PSK (DPSK), DIFFERENTIALLY-ENCODED PSK (DEPSK), QUADRATURE PSK (QPSK), QUADRATURE AMPLITUDE SHIFT KEYING (Q-AS

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 descr iption, power spectral density,
