PROBLEM TO BE SOLVED: To provide an adaptive array antenna receiving device capable of improving an interference wave removing performance without increasing the number of antenna elements. SOLUTION: Adaptive array antenna receiving devices each comprising a plurality of antenna elements 10, a multiplier 102, an adder 104, and a digital signal processing unit 107 are provided as two systems A and B. An out-GI desired wave and an interference wave are removed here and then after it is made possible to regard a plurality of in-GI interference waves as one wave through demodulation by an FFT unit 106 characteristic of an OFDM system, a plurality of in-GI interference waves are removed. Consequently, an antenna element need not be provided for the plurality of in-GI interference waves. COPYRIGHT: (C)2008,JPO&INPIT
