1. Algorithms and Proofs of Concept for Massive MIMO Systems
Sammanfattning : This thesis focuses on algorithms and proofs of concepts in the area of wireless systems operating with a large number of antennas, especially at the base station side.The first studied topic concerns the design and implementation of massive multiple-input multiple-output (MIMO) testbeds, primarily for communications.

2. Optimal Performance of Advanced Radiating Structures
Sammanfattning : Requirements on radiating structures are constantly increasing, demand for faster speed, smaller size, and higher reliability drives today's technical development. However, for electrically small structures, less than half-a-wavelength in size, performance is fundamentally limited by physical size. LÄS MER
3. Electronic properties of complex interfaces and nanostructures
Sammanfattning : This thesis investigates the structural and electronic properties of graphene, polyaromatic hydrocarbon (PAH) molecules, and other carbon-based materials, when interacting with metallic surfaces, as well as under the influence of different types of perturbations. Density functional theory, incorporating van der Waals interactions, has been employed. LÄS MER
4. Computational Tools for Antenna Analysis and Design
Sammanfattning : Many engineers and scientists prevalently use computational tools in electromagnetics, which is also the predominant case for antennas. The ever-increasing number of applications and technologies that employ antennas create a constant demand to improve and extend existing tools and develop new ones. LÄS MER
5. Essays on the term structure of interest rates and monetary policy
Sammanfattning : This thesis consists of four empirical essays, summarized below.In “On Alternative Interest Rate Processes'' the interest rate dynamics for four European countries are studied. There seems to be a positive relation between the interest rate level and the volatility of interest rate changes. LÄS MER
