1. Discrete Stochastic Time-Frequency Analysis and Cepstrum Estimation
Abstract : The theory of stochastic time-frequency analysis of non-stationary random processes has mostly been developed for processes in continuous time. In practice however, random processes are observed, processed, and interpreted at a finite set of time points. READ MORE

2. Estimation and Classification of Non-Stationary Processes : Applications in Time-Frequency Analysis
Abstract : This thesis deals with estimation and classification problems of non-stationary processes in a few special cases.In paper A and paper D we make strong assumptions about the observed signal, where a specific model is assumed and the parameters of the model are estimated. READ MORE

3. Statistical inference and time-frequency estimation for non-stationary signal classification
Abstract : This thesis focuses on statistical methods for non-stationary signals. The methods considered or developed address problems of stochastic modeling, inference, spectral analysis, time-frequency analysis, and deep learning for classification. READ MORE

4. The Non-Linear Instantaneous Least Squares Approach to Signal Parameter Estimation
Abstract : Estimation of parameters of non-stationary signals observed in noise is a challenging and difficult task, motivated by applications such as radar and mobile tele-communication. Here, a novel method for signal parameter estimation named the Non-linear Instantaneous Least Squares (NILS) approach is presented, which can be applied to linear and non-linear signals, and to both uniformly and non-uniformly sampled data.

5. Signal Characterization of Atrial Arrhythmias using the Surface ECG
Abstract : This doctoral thesis is comprised of five parts which deal with different signal processing problems in ECG-based characterization of atrial arrhythmias. Such characterization requires that the ventricular activity has first been cancelled in the ECG. READ MORE
