<p>PROBLEM TO BE SOLVED: To obtain a transmitter/receiver obtaining desired wave by suppressing interference wave regardless of the level difference between the interference wave and the desired wave. SOLUTION: Provided are a transmission device 2 constituted of a first distributer 4 distributing base transmission signals, each phase shifter 8 shifting the phase of a plurality of distributed transmission signals after distribution, a phase shifter control means 7 controlling the phase of each phase shifter 8, each transmission antenna radiating transmission signals corresponding to the signals after phase shifting, a second distributer 3 taking out a part of base transmission signal and a transmitter, and a reception device constituted of a delay means delaying the output of each reception antenna and the second distributer 3, a subtracter 18 with a plurality of weighting coefficients processing interference wave removing with the distribution signal after delaying and an adder 19 adding the subtractor outputs. A part of the adder output of the reception device is fed back to the phase shifted control means 7 of the transmission device.</p> |
