<p>PROBLEM TO BE SOLVED: To provide a technique for improving a characteristic in receiving a packet signal with a known preamble shorter than data in a fading environment.SOLUTION: A reception processing section 24 receives packet signals via a plurality of antennas. A weight vector derivation section 42 derives weight vectors for the packet signals received by the plurality of antennas. The weight vector derivation section 42 updates the weight vectors by an RLS algorithm and resets an inverse correlation matrix in the RLS algorithm in the middle of the packet signals. A multiplication section 40 and a combination section 44 use the derived weight vectors in combining the packet signals received by the plurality of antennas.</p> |
