SYSTEM AND METHOD FOR TRANSMITTING/RECEIVING A SIGNAL IN A MOBILE COMMUNICATION SYSTEM USING A MULTIPLE INPUT MULTIPLE OUTPUT ADAPTIVE ANTENNA ARRAY SCHEME

摘要

Disclosed are a method and a system for transmitting/receiving signals in a mobile communication system using a multiple input multiple output adaptive antenna array scheme. A first receiver calculates a reception weight value b y using a de-spread signal of a reception signal for creating a reception beam of the first receiver and calculates a transmission weight value by using th e calculated reception weight value for creating a transmission beam of the second transmitter, thereby creating feedback information including the transmission weight value. A first transmitter transmits the feedback information to a second receiver. The second receiver receives the feedback information and the second transmitter detects the transmission weight value from the feedback information received in the second receiver, and creates t he transmission beam corresponding to the detected transmission weight value in order to transmit a signal by applying the transmission beam to the signal.< /SDOAB>
