1. Volterra Modeling and Estimation of the Human Smooth Pursuit
Sammanfattning : This thesis treats the mathematical modeling of the human smooth pursuit system using Volterra-Laguerre models. The smooth pursuit system allows for tracking of moving objects. Since it is a complex system including the muscles of the eye, nerves and certain parts of the brain, the system may be impaired if some part is compromised. LÄS MER
2. Characterization and Compensation of Hardware Impairments in Transmitters for Wireless Communications
Sammanfattning : Increasing demands for data rate, energy efficiency and reliability in wireless communications have resulted in the introduction of radio frequency (RF) multiple input multiple output (MIMO) transmitters. However, MIMO transmitters suffer from additional crosstalk impairments along with the power amplifier (PA) and I/Q imbalance distortions observed in single input single output (SISO) transmitters.

3. Characterisation and Modelling of Graphene FETs for Terahertz Mixers and Detectors
Sammanfattning : Graphene is a two-dimensional sheet of carbon atoms with numerous envisaged applications owing to its exciting properties. In particular, ultrahigh-speed graphene field effect transistors (GFETs) are possible due to the unprecedented carrier velocities in ideal graphene. LÄS MER
4. Digital Compensation Techniques for Transmitters inWireless Communications Networks
Sammanfattning : Since they appeared, wireless technologies have deeply transformed our society. Today, wireless internet access and other wireless applications demandincreasingly more traffic. However, the continuous traffic increase can be unbearableand requires rethinking and redesigning the wireless technologies inmany different aspects. LÄS MER
5. Volterra and Algebraic Approaches to the Zero Dynamics
Sammanfattning : The zero dynamics is a property of affi.ne nonlinear systems w hich has been extensively studied during the last decade. Its properties are important in several contexts such as exact linearization, stabilization and sliding mode control. LÄS MER
