Abstract
The demodulator executes a demodulating process on a received radio signal, and generates a demodulation clock in the demodulating process. The first clock oscillator generates a high-rate clock which is at a high rate compared to the demodulation clock. The second clock oscillator generates a low-rate clock which is at a low rate compared to the demodulation clock. The timing generator estimates a rise time of the demodulation clock corresponding to the next reception timing in intermittent reception. Furthermore, the timing generator controls the first clock oscillators substantially in synchronism to the rise time of the demodulation clock.
