Patent ID: 7133439

Claim:
A mobile communication terminal, comprising: a receiver receiving radio signals from base stations; a detector detecting spread codes from said signals received by said receiver, said detector including: a slot timing detector detecting slot timing from the signals received by said receiver, a frame timing and code group detector detecting frame timing and a code group based on the slot timing detected by said slot timing detector from the signals received by said receiver, and a code detector detecting a code based on the slot timing detected by said slot timing detector and the code group detected by said frame timing and code group detector from the signals received by said receiver; a demodulator demodulating the received signals with the spread codes detected by said detector; a decoder decoding data demodulated by said demodulator; and a control unit controlling a cell search process, and stopping signal processing of the cell search in response to detection of an invalid frame timing, code group or code based on information received from the base station.
