1. Visualizing and Controlling Coupling Paths Between Antennas Installed on Common Platforms
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : In this work, a methodology to visualize and mitigate antenna coupling ina systematic way is proposed, which can be used to increase the isolationbetween dierent antenna systems installed on a common platform. Formulationsfor visualizing the coupling in space, based on reciprocity are derivedfrom the reaction theorem and the dierent formulations are compared witheach other through numerical simulations in CST Microwave Studio and bypost-processing in Matlab.

2. Long Range Channel Predictions for Broadband Systems : Predictor antenna experiments and interpolation of Kalman predictions
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Signaler och SystemSammanfattning : The field of wireless communication is under massive development and the demands on the cellular system, especially, are constantly increasing as the utilizing devices are increasing in number and diversity. A key component of wireless communication is the knowledge of the channel, i.e, how the signal is affected when sent over the wireless medium. LÄS MER
3. Channel Prediction for Moving Relays
Uppsats för yrkesexamina på avancerad nivå, Signaler och SystemSammanfattning : In mobile communications, channel side information at transmitters can increasecapacity. For moving relays nodes, local nodes placed on buses and trams in urbanareas, the channel state information is outdated for control delays of severalmilliseconds, as in the LTE system. LÄS MER
