AUTOMATIC GAIN CONTROL OF A RECEIVED SIGNAL USING A POWER TARGET

摘要

The present invention relates to a method and device for performing automatic gain control of a received signal. The method comprises the steps of receiving (S101) the signal and amplifying the received signal on the basis of a difference between a power reference value and actual power of the amplified signal. The method further comprises the steps of determining (S102) signal-to-interference ratio of the received signal and controlling (S103) amplification such that the amplified signal attains a target power level by further taking into account the determined signal-to-interference ratio, which target power level is increased as the determined signal-to-interference ratio decreases.
