PROBLEM TO BE SOLVED: To precisely estimate a weight in adaptive array reception. SOLUTION: An antenna 10 receives a signal including a known part and a data part alternately. A weight estimation unit 20 performs an adaptive algorithm for a known part obtained by an acquisition unit to estimate a weight vector. An array composition unit 50 performs array composition processing on the received known part with the weight vector estimated by the weight estimation unit 20. A weight correction unit 40 corrects the weight vector used for the known part by a weight multiplication unit 60 based upon an array composite signal from the array composition unit 50 to derive a weight vector by which the data part is to be multiplied. The array composition unit 50 performs array composition processing on the received data part with the weight vector corrected by the weight correction unit 40. COPYRIGHT: (C)2009,JPO&INPIT
