  3. 7. Self-organizing Maps for Digital Pre-distortion

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Michail Isaakidis; [2020]
    Keywords : Self-organizing maps; Digital pre-distortion; Technology and Engineering;

    Abstract : Power amplifiers are very important components in the area of wireless communications. However, they are non-linear devices and they seem to achieve high efficiency when they are operating in the non-linear regions, at the cost of being more power-consuming. In order to linearize their behavior, designers have been considering many methods. READ MORE
