Abstract

This paper describes the implementation of a fuzzy logic automatic gain control (AGC) applied to amateur radio communications using ionospheric propagation mode and single side band radio equipment. A fuzzy logic algorithm was directly substituted for the original AGC algorithm, which resulted in an improved signal strength, clarity response and algorithm performance. A comparison between the division and a fuzzy logic based algorithms shows a reduction in RMS gain from 12.45 to 6.45 dB. Moreover, in signal clarity, the fuzzy based AGC algorithm obtained the best no-distortion rank. This implementation proves the feasibility of real-time fuzzy logic based AGC in communication systems
