Coding and Modulation for Digital Television
Binary phase shift keying (BPSK) is a special class of MPSK modulation in which
the modulated signal is allowed to have only M = 2 discrete phase values. In
principle, any two phasor states can be used to represent the binary symbols but
...

Newnes Guide to Radio and Communications Technology
However, phase shift keying (PSK) has many advantages in terms of efficient use
of bandwidth. The problem with phase shift keying is that the receiver cannot
know the exact phase of the transmitted signal to determine whether it is in a
mark ...

The Electrical Engineering Handbook
If we define four signals, each with a phase shift differing by 908 then we have
quadrature phase shift keying (QPSK). We have previously calculated the error
rates for a general phase shift keying signal with M signal points. For QPSK, M 1⁄
