Abstract
A demodulating apparatus that can reduce power consumption significantly compare to conventional cellular phones without the reception quality being degraded. Delay profile measuring is provided in which the delay profile (S,) of the baseband signal is measured while changing the measuring time for measuring the delay profile of the baseband signal, so that the measuring time can be held down to a minimum while avoiding the degradation of the reception power level. Therefore, power consumption can be significantly reduced compared to conventional cellular phones without reception quality being degraded.
