1. 1. 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.

3. 2. Different Digital Predistortion Techniques for Power Amplifier Linearization

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

   Author : Ibrahim Can Sezgin; [2016]
   Keywords : DPD; Digital Predistortion; Forward Behavioral Modeling; Power Amplifier; Non-Linearity; Memory Effect; Volterra Series; Memory Polynomial; Generalized Memory Polynomial; Simplified Volterra Series; Augmented Complexity Reduced Generalized Memory Polynomial; Augmented Complexity Reduced Simplified Volterra; Technology and Engineering;

   Abstract : Linearity and high efficiency are crucial requirements for any power amplifier. However, power amplifiers have high efficiency levels when they are in non-linear regions. To overcome this issue there have been many suggestions in literature, one of the most successful methods is digital predistortion method. READ MORE

4. 3. System Level Modeling and Verification of All-digital Phase-locked Loop

   University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

   Author : Chi Zhang; [2015]
   Keywords : ;

   Abstract : In wirelesscommunication systems, a local oscillator (LO) aims at demodulating radio-frequency signals into baseband signals. The performance of these signals determines the quality of communications which is highly affected by the phase accuracy of local oscillators. READ MORE

5. 4. Modeling of a World Rally Championship Car Damper and Experimental Testing of Its Components

   University essay from KTH/Fordonsdynamik

   Author : Richard Chahine; [2011]
   Keywords : ;

   Abstract : Rally cars are driven on many different types of surfaces. Each type of surface demands a special type of damper setup. In order to achieve optimum performance on the snow covered and icy Swedish roads, the gravel of the Spanish rallies and the smooth tarmac of the German rallies, a large flexibility in the possible damper settings is required.
