This paper presents adaptive predistortion techniques based on a feed-forward neural network (NN) to linearize power amplifiers such as those used in satellite communications. Indeed, it presents the suitable NN structures which give the best performances for three satellite down links. The first lin...
s designed to deliver an organic distortion reminiscent of the early to mid-70s UK voiced amplifiers, cranked up to 10. with the tubes worn down just a little, and maybe a little “browning” of the sound with a Variac. The Presence knob helps dial in the perfect amount of highs for ...
