Abstract:
An apparatus for controlling power in a CDMA system, comprising:K number of transmitting antennas;a CDMA base band/IF transmitter processing an input information signal and outputting M number of IF signals in response to K number of independent data channel gains;K number of RF modules converting the M number of IF signals into K number of RF signals and transmitting the converted K number of RF signals through K number of transmitting antennas;a receiver receiving and processing at least one Mobile Station (MS) signal from at least one corresponding mobile terminal, said receiver outputting K number of power control bits and outputting decoded data; anda processor generating and outputting the K number of independent data channel gains to the CDMA base band/IF transmitter in response to said K power control bits to independently control a power level of each of the K number of RF signals.
