Apparatus and method for power control in digital mobile communication system broadband multi-carrier base station

A multi-carrier power control apparatus for base station in a broadband digital mobile communication system, comprising:

• N digital up-conversion processors, an adder, a data processor, a digital to analog converter, a filter and a transmitter with a voltage controlled attenuator;
• 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 adder, the synthesized signals are sent to the power control module;
• meanwhile, the power control data and the carrier frequency information are sent to the power control module;
• after being processed by the power control module, the signals are outputted through three ways, the signals of one way are respectively sent to N digital up-conversion processors, the signals of another way are sent in turn to the digital to analog converter, the filter and the transmitter with a voltage controlled attenuator, and the up-down slope control data are sent through the other way to the transmitter with a voltage controlled attenuator to be transmitted by the transmitter.
