A reception device according to the present invention is provided with an expander for frequency-converting a reception signal by multiplying a station-transmitted signal output from an oscillator and having a frequency different from a center frequency of the reception signal and the reception signal and outputting an intermediate signal. The oscillator intermittently operates in synchronization with generation timings of short pulse waves included in the reception signal. Thus, the reception device according to the present invention can reduce power consumption more using a UWB communication system. |
