  3. 2. 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

  6. 5. Behavioral Modeling of Power Amplifier with Memory Effect and Linearization Using Digital Pre Distortion

    University essay from Högskolan i Gävle/Elektronik

    Author : Om Prakash Nandi; [2016]
    Keywords : Behavioral Modeling; Power Amplifier; DPD;

    Abstract : This thesis work studied the behavioral modeling, estimation of parameters, model performance and linearization of power amplifier (PA) using Digital Pre Distortion (DPD) technique. PAs are one of the fundamental block in communication systems and also one of the main sources of nonlinearities in the system, as these devices are frequently subjected to signals characterized by considerable bandwidths and non-constant envelopes due to use of modern modulation technique.
