6. Statistical Analysis of Hardware Impairments in Communication Systems
Sammanfattning : This thesis delves into the study of hardware impairments, the inevitable limiting factors in radio frequency (RF) communication systems, and their substantial influence on system performance. It addresses the incongruity between the often stringent requirements imposed by standards and the innate imperfections of analog circuits present in real-world RF electronics. LÄS MER
7. Spectral Mammography with X-Ray Optics and a Photon-Counting Detector
Sammanfattning : Early detection is vital to successfully treating breast cancer, and mammography screening is the most efficient and wide-spread method to reach this goal. Imaging low-contrast targets, while minimizing the radiation exposure to a large population is, however, a major challenge. LÄS MER
8. Modeling and Model Reduction by Analytic Interpolation and Optimization
Sammanfattning : This thesis consists of six papers. The main topic of all these papers is modeling a class of linear time-invariant systems. The system class is parameterized in the context of interpolation theory with a degree constraint. LÄS MER
9. A convex optimization approach to complexity constrained analytic interpolation with applications to ARMA estimation and robust control
Sammanfattning : Analytical interpolation theory has several applications in systems and control. In particular, solutions of low degree, or more generally of low complexity, are of special interest since they allow for synthesis of simpler systems. LÄS MER
10. On hard-decision forward error correction with application to high-throughput fiber-optic communications
Sammanfattning : The advent of the Internet not only changed the communication methods significantly, but also the life-style of the human beings. The number of Internet users has grown exponentially in the last decade, and the number of users exceeded 3.4 billion in 2016. LÄS MER
