Patent ID: 7336726

Claim:
A multi-carrier power control apparatus for base station in a broadband digital mobile communication system, comprising: N digital up-conversion processors, wherein N is an integer; a summing module; a data processor; a digital to analog converter; a filter and a transmitter with a voltage controlled attenuator, and wherein the data processor is a power control module, N-way baseband signals are respectively inputted to the corresponding N digital up-conversion processors, and then outputted from N digital up-conversion processors to the summing module, synthesized signals outputted from the summing module are sent to the power control module to be processed, and meanwhile, power control data and carrier frequency information are sent to the power control module to be processed, and after being processed by the power control module, signals are outputted from the power control module through first, second, and third group of signals after being processed by the power control module, the signals of the first group being respectively sent to the N digital up-conversion processors, the signals of the second group being sent to the digital to analog converter, the filter, the transmitter with the voltage controlled attenuator consecutively, the signals of the third group being up-down slope control data and sent to the transmitter with the voltage controlled attenuator to be transmitted by the transmitter.
