A wireless receiver having improved receiving characteristics is provided. The wireless receiver (151) is provided with an antenna (152) for receiving wireless signals including a modulation signal and a pilot signal having a frequency different from that of the modulation signal; a distributor (159) for distributing the received signal received by the antenna (152) in two directions; a band pass filter (160) for extracting a signal composition corresponding to the pilot signal, from the one signal distributed by the distributor (159); a delay corrector (162) for delaying the other signal distributed by the distributor (159); a quadrature demodulator (163) for multiplying the signal composition from the band pass filter (160) by the other signal delayed by the delay corrector (162) by frequency and for performing quadrature demodulation; and a synthesizer (165) provided before the quadrature demodulator (163), for synthesizing the signal component from the band pass filter (160) with a local oscillation signal having a frequency equivalent to the signal component.
