Abstract
An apparatus and method for controlling a digital AGC in a communication system in which power changes significantly from frame to frame. In the digital AGC controlling apparatus, an SNR estimator estimates an uplink SNR of a next frame. A power measurer measures uplink received power of every frame. A gain calculator estimates uplink power of an nframe using an SNR estimate of an (n−1)frame received from the SNR estimator and a received power measurement of the (n−1)frame received from the power measurer, and calculates a gain to be applied to the nframe in the digital AGC using the uplink power estimate of the nframe.
