PROBLEM TO BE SOLVED: To provide a receiver capable of increasing the accuracy in estimation of carrier frequency error.SOLUTION: The receiver receives a signal which is modulated in a modulation manner to rotate the phase. The phase of a sampling signal is rotated inversely by a rotation amount corresponding to the modulation manner. The correlation values between the signal and predetermined signals are calculated in order. From the correlation values, a maximum values in the maximum correlation values, which are periods divided according to the modulation manner and are rotated by a rotation amount according to the modulation manner, is output in order. The carrier frequency error between a transmitter and the receiver is estimated according to the phase rotation amount among plural maximum correlation values. The phase of the sampling signal is rotated according to the estimated carrier frequency error. |
