Abstract
In a waiting mode after transmission, a radio receiver is operated to convert a radio frequency signal into an intermediate frequency signal of which a signal level is checked. When the signal level is higher than a predetermined level, a reception mode starts for spectrum-despreading the intermediate frequency signal to provide a spectrum-despread signal and demodulating the spectrum-despread signal.
