PURPOSE:To attain effective compensation even when a frequency distortion exists in an interference wave by generating a compensation signal being the same spectrum as that of an interference wave and controlling the characteristic and the amplitude corresponding to the interference wave so as to synthesize the compensation signal into a desired signal. CONSTITUTION:A correlation detection means 101 multiplies a delayed signal of an in-phase data obtained through the identification of the 2nd polarized wave signal B with an error signal to the in-phase and orthogonal data obtained through the identification of the 1st polarized wave signal A to obtain a control signal representing the in-phase and orthogonal components representing the correlation between the signals A and B. A compensation signal generating means 102 multiplies the control signal of each component of the meas 101 with signals decomposing the signal B into the in-phase and orthogonal components respectively, delays the signal B or the output of the result of multiplication, synthesizes the output and the signal B to obtain an output of the compensation signal. A control means 104 controls the compensation signal in response to the pilot carrier level of the signal B in the signal A detected by a detection means 103. A synthesis means 105 synthesized inversely the output of the means 104 to the signal B so as to compensate the interference wave in the signal A.
