Abstract

Software AGC algorithms for narrowband AM/FM and single-sideband integrated receivers are described. Computer simulations were conducted to evaluate the proposed schemes. Results indicate that the AGC performs well and can easily achieve a 100 dB AGC dynamic range, which is enough for most communication systems. This software AGC design was then implemented in the ITT/TI integrated communication, navigation, and identification avionics integrated radio demonstration breadboard. The AGC/squelch software was executed by TI´s micro vector processor breadboard and the 1750A data processor breadboards, interfaced with the zero-IF (intermediate frequency) receiver. The integrated radio concept was demonstrated by the successful execution of the transmit/receive function with a USAF AN/ARC-186 radio set
