Abstract:
A device for controlling transmission power of a mobile station in a multi-carrier CDMA (Code Division Multiple Access) mobile communication system, comprising:a digital mixer that receives multi-carrier signals, divides the multi-carrier signals according to carrier and filters the divided carrier signals; a searcher that interfaces with the digital mixer and separates the divided carrier signals according to carrier signals which have the same path delay; a plurality of fingers, each finger despreading and demodulating the carrier signals which have the same path delay, the carrier signals having the same path delay being input in parallel from the searcher to the fingers, the finger synchronizing its respective demodulated signal with the demodulated signals of the other fingers; and a plurality of parallel/serial (P/S) converters that receive the demodulated signals from the fingers and convert the demodulated signals from parallel to serial signals; a combiner that receives the demodulated serial signals and separates the demodulated serial signals according to cells, and generates a transmission gain control signal based upon power control bits extracted from the separated demodulated signals for a transmission device of a mobile station.
