A mobile communication terminal includes a de-spreader which de-spreads signals received from a base station, a RAKE-synthesizer which RAKE-synthesizes the de-spread signals, a SIR detector which measures a SIR of the received signals, a SIR comparator which compares a SIR of the received signals to a target SIR, a quality detector which measures quality of the received signals at a predetermined interval, a quality comparator which compares the quality of the received signals, transmitted from that quality detector, with target quality, the quality comparator lowering the target SIR, if the quality of the received signals is higher than the target quality, and raising that SIR, if the quality of the received signals is lower than the target quality, and a controller which stores a minimum target SIR therein, and varies the minimum SIR in accordance with a relation between the target SIR and the quality of the received signals. |
