ABSTRACT:
A system and method for adaptive power control of a spread spectrum transmitter of a mobile unit operating in a cellular-communications network having a plurality of mobile units in communication with a base station. In response to a received signal from the mobile unit, the received signal having a first spread-spectrum signal and an interfering signal, an automatic gain control (AGC) circuit within the base station generates an AGC-output signal which is despread buy a base correlator and then processed as a received-power level. The received-power level is then compared to a threshold level level to generate a power command signal. The power command signal is transmitted to the mobile stations as a spread-spectrum signal. The mobile station despreads the second-spectrum signal as a power adjust signal and, responsive to the power adjust signal, increases or decreases the power level of the first spread-spectrum signal.
