Webb22 aug. 2016 · This is where differential quadrature phase shift keying (DQPSK) comes into play. In QPSK, information is conveyed by the absolute phase of each symbol. … Webbp/4 DQPSK (Differential Quadrature Phase-Shift Keying) is a differential format where the bits for a given symbol are determined by the phase change from the previous symbol. " p /4" adds an p /4 offset to the phase changes compared with the phase changes in plain DQPSK. This means there are a total of 8 ideal state positions (compared to the 4 ...
