<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 multi-carrier signals including a plurality of subcarriers via a plurality of antennas. A weight vector derivation section 42 derives weight vectors in subcarrier units for the multi-carrier signals received by the plurality of antennas. The weight vector derivation section 42, in deriving the weight vector for a predetermined subcarrier, uses the signal of that subcarrier and the signals of subcarriers other than that subcarrier as well. A multiplication section 40 and a combination section 44 use the derived weight vectors in combining the multi-carrier signals received by the plurality of antennas in subcarrier units.</p> |
