Abstract
An exemplary automatic gain control device includes: a radio frequency receiver for receiving a plurality of first signals through a plurality of antennas, respectively controlling gains of the plurality of first received signals, and outputting the plurality of the first signals having the controlled gain as a plurality of second signals; a signal saturation detecting unit for outputting a saturation index determination value when the number of plurality of second signals that are greater than a threshold value is greater than a predetermined number; and a gain controlling unit for comparing power values of the plurality of second signals to detect one power value, and outputting a gain value determined based on a detected power value and a saturation index determination value to the radio frequency receiver.
