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

摘要

A method for transmitting/receiving weight information for creating transmission/reception beams in a mobile communication system using a multiple input multiple output adaptive antenna array scheme. The method includes a receiver receiving a predetermined signal, and differentially providing weights to a first scheme and a second scheme for minimizing an error between the received signal and a predetermined reference signal, thereby obtaining a minimum error value. The receiver generates a despread signal by despreading the received signal, produces a reception weight for creation of a reception beam by the receiver through calculation using the despread signal and the minimum error value, and produces a transmission weight for creation of a transmission beam by a counterpart transmitter through calculation using the reception weight and the minimum error value.
