Abstract: 본 발명은 적응형 뱅뱅 제어 방식의 순차적 분산 협력 빔포밍 장치 및 방법에 관한 것으로, 무선통신 시스템에서 분산된 단말들의 다중 사용자를 지원하는 상향링크 시스템에서, 초기 위상 로 공통의 협대역 메시지 m(t)를 빔포밍하여 협력통신 기법으로 분산 송신 빔포밍(distributed transmit beamforming)을 수행할 때, 수신단으로부터의 1비트 피드백 신호를 통해 각 단말들의 반복적인 위상 조정을 수행함으로써, 수렴하는 수신신호 강도(RSS:Received Signal Strength) 값의 수렴속도를 기존 방식보다 향상시키는 N 개의 송신 단말들; 및 적응형 뱅뱅 제어 기법을 사용하여 (n+1) 번째 시간의 수신 신호 강도(RSS)를 측정하고 그 값이 n번째 시간까지 가장 컸던 수신신호 강도 값을 비교하여 그 중 큰 값을 저장한 후, (n+1) 번째 시간의 수신 신호 강도 값이 더 크면 '1', 작으면 '0'인 1비트의 피드백 정보를 생성한 후, 상기 N개의 송신단말들로 브로드캐스트 방식으로 1bit feedback 신호를 피드백하는 수신기로 구성된다.

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.
