Abstract  Abstract

Apparatus for controlling the adaptive power of a spread spectrum transmitter of a mobile station operating in a cellular communication network using spread spectrum modulation. A base station transmits a generic spread spectrum signal and an automatic phase control information data signal. The mobile station includes an acquisition circuit (101, 102, 103) allowing it to acquire and decode the generic spread spectrum signal, a detector (104) for detecting a power level received from the generic spread spectrum signal , a detector (104) for decoding the automatically phase controlled data signal as a threshold, a differential amplifier (106) which generates a comparison signal by comparing the received power level with the threshold, a transmitter (42) which transmits a spread spectrum signal from the transmitter, an antenna and a variable gain device (111) responsive to the comparison signal indicating an increase or decrease to adjust the power level of the transmitter based on the spectrum signal spread of the transmitter.
