6. Estimation and Performance Analysis of Wireless Multiple Antenna Communication Channels
Sammanfattning : The focus of this thesis is on channel estimation in wireless communication systems that employ multiple antennas.The thesis is divided into two parts, whereof the first part addresses theproblem of parameter estimation of distributed sources. Due to, e.g. LÄS MER
7. MIMO Systems with Residual Hardware Impairments
Sammanfattning : Recent years have witnessed an unprecedented explosion in mobile data traffic, due to the expansion of numerous types of wireless devices, which have enabled a plethora of data-hungry applications. Novel techniques, such as large-scale multiple-input multiple-output (MIMO) systems, represent potential candidates to support the ever-growing demands. LÄS MER
8. Antennas and Propagation from a Signal Processing Perspective
Sammanfattning : This thesis studies several topics within the area of antennas and propagation from a signal processing perspective. However, theory and methods from electromagnetics and communications have also been used, contributing to an interdisciplinary character of the thesis. LÄS MER
9. Capacity Analysis and Receiver Design in the Presence of Fiber Nonlinearity
Sammanfattning : The majority of today's global Internet traffic is conveyed through optical fibers. The ever-increasing data demands have pushed the optical systems to evolve from using regenerators and direct-direction receivers to a coherent multi-wavelength network. LÄS MER
10. Predictor Antennas : Enabling channel prediction for fast-moving vehicles in wireless broadband systems
Sammanfattning : Many advanced transmission techniques utilize channel state information (CSI) at the transmitter (CSIT) to improve throughput, spectral efficiency, power efficiency, and other performance metrics. Estimating CSI accurately is important to fully benefit from many of these techniques. LÄS MER
