Radio Resource Management based on Genetic Algorithms for OFDMA Networks.
(Queen Mary University of London, 2012-01)
OFDMA will be the multiple access scheme for next generation networks, including LTE and LTE-A. These networks will provide higher data rates than now, up to several hundred Mbps. These new networks, using a higher carrier ...
Research and design of non-Foster active metamaterials
During this PhD study, metamaterials incorporating active devices such as varactors and non-Foster circuits, were researched and designed. Starting from the research on tuneable metamaterials, an electronically controlled ...
Coordinate Transformation Based Electromagnetic Design and Applications.
(Queen Mary University of London, 2012-10)
The main objective of this thesis is to take one step forward to practical and realisable devices for antenna and microwave engineering, using the technique of discrete coordinate transformation (DCT), which is a practical ...
Wireless Links for Telecare and Telemedicine Applications using Compact Body-Worn Antennas.
(Queen Mary University of London, 2013-06)
This thesis concerns the design of body-centric wireless communications for short-range indoor Telecare/Telemedicine applications. Such communications are starting to be used to convey key, relatively low data-rate body-sensor ...
Design and Time-domain Analysis of Antenna Array for UWB Imaging Application.
(Queen Mary University of London, 2014-06)
UWB technology has been developing in imaging applications. For security imaging applications, it is vital to detect and image metallic targets concealed in bag at airports, subway stations or other public environments. ...
