1. Linear Models of Nonlinear Systems
Abstract : Linear time-invariant approximations of nonlinear systems are used in many applications and can be obtained in several ways. For example, using system identification and the prediction-error method, it is always possible to estimate a linear model without considering the fact that the input and output measurements in many cases come from a nonlinear system.

2. Inference techniques for stochastic nonlinear system identification with application to the Wiener-Hammerstein models
Abstract : Stochastic nonlinear systems are a specific class of nonlinear systems where unknown disturbances affect the system's output through a nonlinear transformation. In general, the identification of parametric models for this kind of systems can be very challenging. READ MORE

4. System Modeling Using Basis Functions and Application to Echo Cancelation
Abstract : This thesis concerns modeling of linear and nonlinear dynamic systems, where the applied models can be described by basis function expansions. In the first part of the thesis, the investigated model (or filter) structures and parameter estimation algorithms are described. READ MORE

5. Behavioural Modelling of Radio Frequency Power Amplifiers : An Evaluation of Some Block Structure and Neural Network Models
Abstract : This work considers behavioral modelling of radio frequency power amplifiers. Due to the use of modern digital modulation methods power amplifiers are nowadays subjected to signals having a considerable bandwidth and a fast changing envelope. READ MORE
