6. Analysis of Some Methods for Identifying Dynamic Errors-in-variables Systems
Sammanfattning : A system where errors or noises are present on both the inputs and the outputs is called an errors-in-variables (EIV) system. EIV systems appear in industrial and agricultural processes, medical sciences, economical systems, biotechnology, as well as in many other areas. LÄS MER
7. Robust Low-Cost Multiple Antenna Processing for V2V Communication
Sammanfattning : Cooperative V2V communication with frequent, periodic broadcast of messages between vehicles is a key enabler of applications that increase traffic safety and traffic efficiency on roads. Such broadcast V2V communication requires an antenna system with omnidirectional coverage, which is difficult to achieve using a single antenna element. LÄS MER
8. Blind Adaptive Extraction of Impulsive Signatures from Sound and Vibration Signals
Sammanfattning : The two questions in science ``why" and ``how" are hereby answered in the context of statistical signal processing applied to vibration analysis and ultrasonic testing for fault detection and characterization in critical materials such as rolling bearings and thin layered media. Both materials are of interest in industrial processes. LÄS MER
9. A Cosmic Quest for New Worlds. Characterising Exoplanet Signals via Radial Velocity and Transit Photometry
Sammanfattning : Since the first unambiguous detection of a planet around a Sun-like star, the interest in the new and exciting field of exoplanets has grown immensely. New and exciting developments are seen at a pace unparalleled for most subfields of astronomy. LÄS MER
10. Adaptive blind deconvolution using third-order moments : exploiting asymmetry
Sammanfattning : This thesis focuses on the use of third-order statistics in adaptive blind deconvolution of asymmetric impulsive signals. Traditional methods are typically based on fourthorder moments, which can discriminate signals with heavy-tailed probability functions (i.e. `spiky' signals) from corresponding filtered versions.
