An In-depth Study of Offset Quadrature Phase-shift Keying

This book provides an in-depth description of the why and how of offset quadrature phase-shift keying (QPSK). The book starts with time-domain and frequency-domain descriptions of offset QPSK using examples, which explain the benefits of the offset. The topics move on to detection, synchronization, differential detection, equalization, and offset QPSK’s relationship to minimum shift keying and other closely related continuous phase modulations (CPMs). Detailed examples illustrate each concept. A large number of plots and figures complement mathematical derivations and analyses.

The book is written for multiple audiences: the practicing communications engineer who needs a technical reference for offset QPSK; researchers who need a reference for the analysis techniques most suitable for offset QPSK; and graduate research assistants looking to get started with offset QPSK.
