1. Experimentally Based HFET Modeling for Microwave and Millimeter Wave Applications
Abstract : Transistor models are very important in the design of Monolithic Microwave Integrated Circuits (MMICs). Circuit simulations based on accurate transistor models are one of the keys to high circuit yield. Transistor models can also be used to trace problems in the device fabrication processes. READ MORE

2. Modeling and Estimation of Phase Noise in Oscillators with Colored Noise Sources
Abstract : The continuous increase in demand for higher data rates due to applications with massive number of users motivates the design of faster and more spectrum efficient communication systems. In theory, the current communication systems must be able to operate close to Shannon capacity bounds. READ MORE

3. Contributions to Signal Processing for MRI
Abstract : Magnetic Resonance Imaging (MRI) is an important diagnostic tool for imaging soft tissue without the use of ionizing radiation. Moreover, through advanced signal processing, MRI can provide more than just anatomical information, such as estimates of tissue-specific physical properties. READ MORE

4. Optimal Detectors for Transient Signal Families and Nonlinear Sensors : Derivations and Applications
Abstract : This thesis is concerned with detection of transient signal families and detectors in nonlinear static sensor systems. The detection problems are treated within the framework of likelihood ratio based binary hypothesis testing. READ MORE

5. AURALIZATION, PERCEPTION AND DETECTION OF TYRE–ROAD NOISE
Abstract : Due to improvements in combustion engines and electric engines for cars, tyre noise has become the prominent noise source at low and medium speeds. Models exist that simulate the noise produced by a rolling tyre, as do models that auralize specific traffic situations from a basic data set. READ MORE
