Abstract
A system and method for adjusting the power control target for a spread-spectrum communication systemis disclosed. A preferred embodiment comprises correcting a power control targetbased upon the difference between a filtered series of actual error signalsand the expected number of errorsover a properly determined time window. By using a filtered series of actual error signals, the power control target update step-size is adaptive to the channel conditions, and the power-rise is reduced, thereby reducing power requirements and signal dropouts. The invention finds application, for example, in personal communication devices such as cellular telephones and may be implemented using a digital signal processor (DSP).
