PROBLEM TO BE SOLVED: To make small the processing delay of a receiver equipped with adaptive array antennas. SOLUTION: A BB input unit 116 inputs a baseband received signal 300. An initial weight data setting portion 12 establishes a weighting factor 322 used in a training signal 302 zone as an initial weighting factor 320. A gap correction portion 16 corrects a control weighting factor 310 by a gap error signal 316 and outputs an update weighting factor 318 of the result. A weight change portion 18 chooses the initial weighting factor 320 in the training signal 302 zone, chooses the update weighting factor 318 in the data signal zone and outputted as a weighting factor 322. After weighting the baseband received signal 300 by the weighting factor 322, a composite portion 118 adds them. COPYRIGHT: (C)2007,JPO&INPIT
