摘要：
A method and apparatus for adjusting the gain of an amplifier (202) in a communication receiver comprising: estimating the power of a time domain signal (307); estimating the power distribution on one or more sub-carriers of a frequency domain signal (309) transformed from the time domain signal; and generating a gain control signal for the amplifier based on the estimated power of the time domain signal and the power distribution on sub-carriers of the frequency domain signal (311).
