Abstract:
A diversity transmission method and a transmitter of a base station using the same is provided in a mobile communication system. For this purpose, the diversity transmission method for controlling power of transmit antennas when the transmitter transmits a signal to a mobile terminal using a plurality of antennas includes (a) receiving feedback information concerning the antenna having the best channel status from the mobile terminal, (b) increasing power allocation of a selected antenna according to the feedback information by a predetermined amount and decreasing power allocation of a non-selected antenna by a predetermined amount, and (c) transmitting the signal to the mobile terminal using the power allocation controlled in (b).
