A mobile communication terminal (150) includes a de-spreader (11) de-spreading signals received from a base station, a RAKE-synthesizer (12) which RAKE-synthesizes the de-spread signals, a SIR detector (17) measuring a SIR of the received signals, a SIR comparator (18) comparing a SIR of the received signals to a target SIR, a quality detector (13) measuring quality of the received signals, a quality comparator (15) comparing the quality of the received signals 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 target SIR, if the quality of the received signals is lower than the target quality, and a controller (20) 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. |
