Summary:An AGC system in a receiver adjusts the front-end gain not only based on the received sector power level, but also based on the strength of the present interference. When there is no presence of strong electromagnetic interference, the front-end gain of the receiver is set at a high level so that the receiver is maintained at a high sensitivity level. The receiver is operable at a normal current mode and a current saving mode. The receiver is set to run at the normal mode when the received sector power is lower than a certain predetermined level or when a strong interference is present.
