M-PSK (M-ary Phase Shift Keying) modulation is used in a wide variety of communications systems. Use of M-PSK is widespread in wireless networking standards, telephony links, cellular telephony, digital television standards, fiber-optic communications, mobile communications, and military communications. Systems which use M-PSK can be found worldwide in terrestrial, satellite, and deep-space applications. Despite the ubiquitous use of M-PSK, some coherent M-PSK receiver structures have evolved very little since the Costas loop was invented in the 1950s. In this groundbreaking book, new...
