摘要
A demodulation circuit demodulates a differential phase shift keying (DPSK) modulated received signal. A phase difference data generator compares phase data representing a phase of the received signal input at every predetermined sampling time with previous phase data preceding by one symbol time to generate phase difference data representing a phase shift amount of the phase data. A symbol selection unit evaluates the phase difference data generated at every sampling time to select as a symbol.
