<p>Decoded data (7) are obtained by decoding a PCH (paging channel) by means of an RF receiver (3), and A/D converter (4), a correlator (5), and a decoder (6) by performing intermittent receiving operations during stand-by time. An intermittent reception control circuit (16) discriminates the presence/absence of paging data in the PCH based on control information near the lead edge of the PCH and, when no paging data exist, reduces the power consumption of intermittent reception by quickly stopping the functions of the receiver (3), converter (4), correlator (5), and decoder (6). Therefore, the stand-by time of battery-operated digital radio communication equipment can be prolonged.</p> |
