WIRELESS COMMUNICATION DEVICE AND CONTROL METHOD

摘要

A wireless base station (100) in the present invention is equipped with a judgment unit (150) that compares a first signal quality of a first output signal (y1[k]) which is output by an adaptive array antenna (110) and a second signal quality of a second output signal (y2[k]) which is output by an adaptive equalizer (120) and judges whether the improvement effect of the second signal quality with respect to the first signal quality is below expectation. When the judgment unit (150) judges that the improvement effect is below expectation, a control unit (160) stops power supply to the adaptive equalizer (120) and the calculation of an equalization weight (c*) by a weight calculation unit (140), and outputs the first output signal (y1[k]) as the output signal (Out) of a receiver (101).
