Patent ID: 8213541

Claim:
A receiving apparatus, comprising: a receiver which receives a plurality of multicarrier signals corresponding respectively to a plurality of antennas wherein a pilot signal is assigned to at least one subcarrier in the multicarrier signals; a derivation unit which derives amounts of phase rotation for the plurality of multicarrier signals received in said receiver, respectively: a rotation unit which rotates a phase of weight vectors to be multiplied by the plurality of multicarrier signals received in said receiver, by the amounts of phase rotation derived in said derivation unit; and a combining unit which weights respectively the plurality of multicarrier signals received in said receiver, with the weight vectors rotated by said rotation unit and which combines results of weighting, wherein said combining unit determines the combined results, said derivation unit including: means for executing remodulation based on the results determined by said combining unit and a channel characteristic and deriving a first phase difference between the plurality of multicarrier signals received in said receiver and a result of the remodulation; means for executing remodulation based on a value of the pilot signal and the channel characteristic and deriving a second phase difference between the plurality of multicarrier signals received in said receiver and a result of the remodulation; and means for deriving an amount of phase rotation based on the first phase difference and the second phase difference.
