Abstract:
A determiner determines whether or not a mobile communication terminal is in a standby mode. A fast Fourier transform calculator demodulates a signal which is received at the mobile communication terminal. A controller causes the fast Fourier transform calculator to vary at least one of a frequency range for fast Fourier transform or a number of frequency samples used by the fast Fourier transform calculator, depending on determination by the determiner. Preferably, the controller is adapted to cause the fast Fourier transform calculator to vary at least one of the frequency range for fast Fourier transform or the number of frequency samples used by the fast Fourier transform calculator based on information about frequencies used in communication from a radio base station to the mobile communication terminal and notified from the radio base station.
