An automatic gain control (AGC) system (100) for a controlled gain receiver (1101) includes a magnitude generator (160) and a gain corrector (170). The magnitude generator (160) generates a binary voltage squared signal (165) having a binary value that is directly proportional to a recovered signal power...http://www.google.com/patents/US6996383?utm_source=gb-gplus-sharePatent US6996383 - Digitized automatic gain control system and methods for a controlled gain receiver
