摘要： A demodulating unit demodulates a differential M-phase shift keying signal light by causing delay and interference. A phase-error detecting unit detects an error of a control phase amount of the delay and the interference caused by the demodulating unit. A control unit adjusts the control phase amount to a predetermined phase amount based on the error. A data processing unit monitors an error state of data signal that is demodulated by the demodulating unit. The control unit changes the control phase amount from the predetermined amount when the error state is in a predetermined state, and determines a reception state of the differential M-phase shift keying signal light based on an error that is detected after the control phase amount is changed.
