Abstract: There is provided a wireless receiver. The wireless receiver includes an IQ modulator configured to generate an in-phase signal and a quadrature-phase signal from input signals modulated by a frequency modulation scheme and a modulation scheme converter configured to convert a modulation scheme of the in-phase signal and the quadrature-phase signal outputted from the IQ modulator into an amplitude modulation scheme. Further, the wireless receiver includes a bandpass filter configured to pass bandpass signals in which the modulation scheme is converted into the amplitude modulation scheme by the modulation scheme converter.
