ABSTRACT:
An apparatus and method for controlling power in a CDMA system using antenna diversity. The power control apparatus comprises a CDMA base band/IF transmitter for processing an information signal to output K IF signals, K RF modules for converting the K IF signals from the CDMA base band/IF transmitter into K RF signals and transmitting the converted K RF signals through K transmitting antennas, a receiver for receiving a signal from a mobile terminal through a receiving antenna and processing the received signal to output K power control bits and decoded data, and a processor for generating K data channel gains in response to the K power control bits from the receiver and outputting the generated K data channel gains to the CDMA base band/IF transmitter to control transmission powers of the K transmitting antennas. According to the present invention, the transmission power control operation can individually be performed with respect to antennas at the transmitting stage of a base station in consideration of different channel environments.
