METHOD AND SYSTEM OF BEAMFORMING A BROADBAND SIGNAL THROUGH A MULTIPORT NETWORK

摘要

PURPOSE: A method and a system for beam-forming a wideband signal through a multiport network are provided to amplify a phase-shifted signal which dynamically controls and a transmission signal. CONSTITUTION: A system determines phase difference between received signals of couplers during reception time interval(1210). The system generates signals from a modulation signal in transmission time interval(1220). The system amplifies the signals by amplifiers(1230). The output of each amplifier is inputted to a first port of a multiport network(1240).
