An automatic gain control (AGC) system and corresponding method is configured to increase signal to noise which may be referred to as signal to noise ratio in a receiver. The AGC system includes: a signal level detector for determining a signal level for a desired signal; a wideband signal detector for determining a wideband signal level of a wideband signal, the wideband signal being indicative of an interfering signal being present; and a controller coupled to both detectors and configured to provide one or more AGC signals to the receiver to establish a gain setting for the receiver, wherein an initial AGC setting for the receiver is based on the signal level, and AGC adjustments, based e.g., on one or more of the signal level and the wideband signal level, are provided such that an adjusted AGC setting for the receiver increases the signal to noise. |
