Abstract

The embodiments disclose a method and apparatus for automatic gain control. The apparatus comprises a first gain controlled element, a second gain controlled element, a first gain control device, a second gain control device and a first simulator. The first gain controlled element and the second gain controlled element each has a signal input, a gain control input and a signal output. The first gain controlled element and the second gain controlled element are coupled in series and one or more power elements coupled between the first gain controlled element and the second gain controlled element. The signal input of the first gain controlled element constitutes an input of the automatic gain control apparatus. The first gain control device has a pre-detection input which is coupled to the signal input of the first gain controlled element and an output which drives the gain control input of the first gain controlled element. The second gain control device has a pre-detection input and an output which drives the gain control input of the second gain controlled element. The first simulator is coupled between the signal input of the first gain controlled element and the pre-detection input of the second gain control device, which is used to simulate frequency response of the one or more power elements between the first gain controlled element and the second gain controlled element, such that a signal received by the pre-detection input of the second gain control device is matched with a signal received by the signal input of the second gain controlled element.
