Abstract:
1. A radio communication apparatus comprising: a receiver configured to receive a radio signal containing a desired signal from a transmission side radio communication apparatus and an interference signal from an interference source; and a controller configured to control the receiver, wherein the receiver comprises: a second output signal outputted by the adaptive equalizer is outputted as an output signal of the receiver, the radio communication apparatus further comprising: a determination unit configured to compare a first signal quality of the first output signal with a second signal quality of the second output signal to determine whether an improvement effect of the second signal quality with respect to the first signal quality is equal to or smaller than a desired level, wherein when the determination unit determines that the improvement effect is equal to or smaller than the desired level, the controller stops power supply to the adaptive equalizer and calculation of the equalization weight in the weight calculator and causes the first output signal to be outputted as the output signal of the receiver.
