Patent ID: 7062289

Claim:
A multi-carrier power control apparatus for base station in a broadband digital mobile communication system, comprising: N digital up-conversion processors, a data processor, an adder, a digital to analog converter, a filter and a transmitter with a numerical controlled attenuator; wherein N-way baseband signals are respectively inputted to the N digital up-conversion processors, meanwhile, the power control data and the carrier frequency information are sent to the data processor and processed by the data processor, and then the dynamic power level data are respectively outputted from the data processor to N digital up-conversion processors, and the data outputted from N digital up-conversion processors are transferred to the adder, the synthesized data are sent in turn to the digital to analog converter, the filter and the transmitter with a numerical controlled attenuator, meanwhile, the up-down slope control data are also outputted from the data processor to the transmitter with a numerical controlled attenuator to be transmitted by the transmitter.
