Phase-Shift Keying, PSK

In digital (radio) transmission, a method for modulating a digital signal onto an analog carrier. Coding strategies for better transmission performance (higher data capacity) encompass higher-order modulation like QPSK (quadrature PSK), DBPSK (differentially binary PSK), DQPSK (differentially quadrature PSK), and further D8PSK and D16FSK.
