Provided is a wireless receiver capable of realizing multi-band and multi-mode operations while reducing an electric power consumption of an RF analog local oscillator. A wireless receiver (100) comprises: a local oscillator (101) for discontinuously changing a band of a local oscillation signal corresponding to a frequency band of an RF signal to be received and outputting the local oscillation signal; frequency converter (102) for converting the RF signal into an IF signal by using the local oscillation signal and outputting the IF signal; and a demodulator (103) for demodulating the IF signal. The local oscillator (101) detects a frequency variation range of the local oscillation signal, obtains a frequency equivalent to an integral multiple of a symbol rate from the frequency variation range, and outputs the local oscillation signal having a local oscillatory frequency, causing a center frequency of a channel to be received, which channel is included in the intermediate frequency signal, to be equivalent to the integral multiple of the symbol rate.
