Abstract:
1. A receiving apparatus, comprising (i) a received signal level determination section for detecting a power level of a received signal; and (ii) a correlation detection section for detecting a correlation between the received signal and a predetermined reference signal, the receiving apparatus switching between reception standby states as required, said reception standby states, including: a normal operation mode in which a shift to a reception state is determined in accordance with whether or not the correlation is detected by the correlation detection section; and a low power consumption mode in which the shift to the reception state is determined in accordance with whether or not a received signal power level not less than a predetermined value is detected by the received signal level determination section, wherein: the normal operation mode and the low power consumption mode are switched between each other in accordance with the power level of the received signal, which power level is detected by the received signal level determination section.
