Synchronization in Coherent M-PSK Receivers

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 structures for use within coherent M-PSK receivers are presented. These include carrier lock detectors, carrier phase detectors, and SNR (Signal to Noise Ratio) estimators. The aforementioned structures are thoroughly analyzed and compared to previously available structures and it is shown that they have significant performance advantages and have immediate applications for use in M-PSK systems. Therefore, this book is indispensable to any scientist or engineer who is tasked with the research or development of M-PSK communications systems.
