Abstract

A method and apparatus for controlling a signal transmission power. The method of the present invention includes the steps of demodulating a received signal (401) to produce a demodulated signal (407) and distorting the demodulated signal (412) to produce a distorted demodulated signal (413). The demodulated signal (412) can be distorted by, for example, adding noise. A
signal quality measurement, such as signal-to-noise ratio, is then determined (416, 418, 502, 602) based on the distorted demodulated signal rather than the demodulated signal. An adjustment in the transmission power is then requested (420, 506, 508) based on the signal quality measurement of the distorted demodulated signal.
