Abstract
An impulse radio communication device includes a wave detector for generating a detected signal, a switching section for selecting either a received signal or the detected signal in accordance with an external control signal and outputting it as a demodulation target signal, a reference waveform generating section synchronized with the demodulation target signal and generating a reference waveform signal having a different waveform in accordance with the external control signal, a demodulator for generating a demodulated signal from the demodulation target signal in accordance with the reference waveform signal, and a decoding section for decoding received data from the demodulated signal. This impulse radio communication device switches the demodulation target signal and the reference waveform signal simultaneously in accordance with a receiving and synchronizing state. This makes it difficult that synchronization is pulled in a correlation position having low electric power, and can reduce a acquisition time.
