Abstract
An automatic gain control (AGC) system ( ) for a controlled gain receiver ( ) includes a magnitude generator ( ) and a gain corrector ( ). The magnitude generator ( ) generates a binary voltage squared signal ( ) having a binary value that is directly proportional to a recovered signal power of an intercepted signal ( ). The gain corrector ( ) determines an adjustment of a gain control value ( ) as a multiple of increments that are approximately 3 decibel (dB), by shifting ( ) a reference threshold by one or more bits and comparing ( ) the shifted reference threshold to the binary voltage squared signal. An initial setting of a state of a step attenuator ( ) during a track mode ( ) is determined during a warm up mode ( ) by comparing the binary voltage squared signal ( ) to two different thresholds ( ).
