ABSTRACT:
Disclosed is a wireless communication apparatus which synthesize signals received from a plurality of antennas to separate the signals into synthesis signals of a plurality of logical channels. The apparatus has a first phase corrector correcting a phase of a reception signal by estimating an amount of phase correction by a frequency offset of each reception signal from the plurality of antennas; a synthesizer synthesizing reception signals after phase correction by the first phase corrector to separate the reception signals into synthesis signals of a plurality of logical channels; and a second phase corrector correcting a phase of a synthesis signal by estimating an amount of phase correction by a residual frequency offset after phase correction by the first phase corrector based on the synthesis signal synthesized by the synthesizer.
