RADIO RECEIVING APPARATUS, MOBILE STATION APPARATUS, BASE STATION APPARATUS, AND RADIO RECEIVING METHOD

摘要

A radio receiving apparatus, a radio receiving method, and mobile station and base station apparatuses having the radio receiving apparatus, wherein the circuit scale of the whole apparatus has been reduced and the size and cost of the apparatus have been also reduced without increasing the loads of processings. A phase control part (290) holds the phase rotation amounts of subcarrier signals that are caused by a delay in sampling timing of a second antenna relative to a first one and that are predetermined in accordance with both the number of the reception antennas of the radio receiving apparatus and the frequencies of the subcarriers. The phase control part (290) causes N subcarrier signals outputted from an FFT (240-2) associated with the second antenna to rotate in phase by the respective phase rotation amounts held by the phase control part (290).
