Patent abstract
In carrying out a cell search, the received-signal level (RSSI) at each frequency is measured in the first place, by implementing asynchronous detection in steps of a predetermined frequency-step width over a predetermined search frequency range (from Fini to Fend), After measuring the RSSI, a cell search is carried out by implementing synchronous-detection processing over the frequency range that has a center frequency where the received-signal level is higher than a threshold value and that has the frequency-step width, it is an object of the present invention to obtain a communication terminal unit that can reduce a cell-search time.
