RECEIVER

PROBLEM TO BE SOLVED: To provide a receiver for obtaining the correction amount of phase deviation and the correction amount of amplitude deviation by detecting the phase deviation and the amplitude deviation independently. SOLUTION: The phase deviation and amplitude deviation detection processing 300 detects phase deviation (Δ ) and amplitude deviation (g) independently, by a multiplication section 130 for squaring a digital signal of an in-phase signal (Sr), a multiplication section 131 for multiplying the in-phase signal (Sr) and an orthogonal signal (Si), a multiplication signal 133 for squaring the real part (Pr) of a pilot signal, a multiplication section 138 for squaring the imaginary part (Pi) of the pilot signal, a processing section 150 for calculating a square-root of the output of a subtraction 149 and outputting amplitude deviation (g), a processing section 151 for calculating or reading out the reciprocal and constant of the amplitude deviation (g), a multiplication section 152 for multiplying the output of the processing section 151 and the output of the multiplication section 142, and a processing section 153 for calculating or reading out the inverse sine function of the output of the multiplication section 152 and outputting the phase deviation (Δ ).
