Abstract: PURPOSE: A multi-antenna transmitter, a multi-antenna receiver, and a control method of a wireless connection system are provided to obtain a multi-transmission gain based on a small amount of feedback information in an environment where a signal-to-noise ratio is high and a transmission terminal comprises a plurality of antennas. CONSTITUTION: A control unit is connected to multiple antennas. The control unit receives a first feedback in order to form a first beamformer (100) from a receiver. The control unit forms the first beamformer based on the received first feedback. The control unit receives a second feedback necessary to form a second beamformer from the receiver based on the first beamformer. The control unit forms the second beamformer based on the received second feedback.

Abstract: PURPOSE: A sequential distribution cooperative beam-forming method of an adaptive bang-bang control method is provided to repeatedly control a phase of each terminal through one bit feedback signal from a reception end. CONSTITUTION: A receiver(10) measures the RSS(Received Signal Strength) of n+1 time by using an adaptive bang-bang control method. The receiver stores a large value by comparing the measured value with an RSS value. When the RSS value of the n+1 time is greater than the RSS value, the receiver generates feedback information. When the RSS value of the n+1 time is smaller than the RSS value, the receiver generates the feedback information of one bit. The receiver transmits the feedback signal of the one bit to N transmission terminals in a broadcast method.
