1. Channel Estimation in Wireless Communication Systems Employing Multiple Antennas
Sammanfattning : Antennas that are able to adaptively direct the transmitted (and received) energy are of great interest in future wireless communication systems. The directivity implies reduced transmit power and interference, and also a potential for increased capacity. LÄS MER
2. Multiple Antenna Terminals in Realistic Environments - A Composite Channel Modeling Approach
Sammanfattning : For evaluation of specific antenna arrangements in wireless communication systems we need physical channel models that take into account also the directional domain of the propagation channel. In this thesis we investigate, validate and propose a practical approach to wireless channel modeling and, particularly, to mobile communication systems. LÄS MER
3. Influence of Fiber Nonlinearity on the Capacity of Optical Channel Models
Sammanfattning : The majority of today’s global Internet traffic is conveyed through optical fibers. The ever-increasing data demands has pushed the optical systems to evolve from using regenerators and direct-direction receivers to a coherent multi-wavelength network. LÄS MER
4. Prediction of Mobile Radio Channels : Modeling and Design
Sammanfattning : Prediction of the rapidly fading envelope of a mobile radio channel enables a number of capacity improving techniques like fast resource allocation and fast link adaptation. This thesis deals with linear prediction of the complex impulse response of a channel and unbiased quadratic prediction of the power. LÄS MER
5. Baseband Processing for 5G and Beyond: Algorithms, VLSI Architectures, and Co-design
Sammanfattning : In recent years the number of connected devices and the demand for high data-rates have been significantly increased. This enormous growth is more pronounced by the introduction of the Internet of things (IoT) in which several devices are interconnected to exchange data for various applications like smart homes and smart cities.
