1. Investigating and Enhancing Performance of Multiple Antenna Systems in Compact MIMO/Diversity Terminals
Abstract : Today, owners of small communicating device are interested in transmitting or receiving various multimedia data. By increasing the number of antennas at the transmitter and/or the receiver side of the wireless link, the diversity/Multiple-Input Multiple-Output (MIMO) techniques can increase wireless channel capacity without the need for additional power or spectrum in rich scattering environments.

2. Antenna Evaluation for Vehicular Applications in Multipath Environment
Abstract : Antennas are essential components in any wireless communication system. To evaluate them is challenging, especially when new technologies are emerging.Future intelligent transport systems, where vehicular communications play an important role will cover important aspects such as traffic safety and traffic efficiency.

3. On the Benefits of Moving Relay Nodes in Wireless Networks
Abstract : In order to meet the needs of high speed wireless connections, a new generation of cellular network, i.e., Long Term Evolution (LTE) has been standardized and deployed by the 3rd Generation Partnership Project (3GPP). By employing ad- vanced smart antenna techniques, fast channel dependent scheduling, adaptive coding and modulation, etc. READ MORE

4. Integrated Transmitters for Cellular User Equipment–Wideband CMOS Power Amplifiers and Antenna Impedance Tuners
Abstract : The digital cellular systems era started about thirty years ago with the release of the first digital cellphones. These first digital cellphones were very different from today’s slim and esthetic cellular pocket computers. They were not mass-produced in million units a day, and they were designed for radio performance rather than appearance. READ MORE

5. Characterization of Small Antennas & Wireless Devices for MIMO Systems in Rich Isotropic Multipath & Random Line-of-Sight
Abstract : The current thesis is about over-the-air (OTA) performance characterization of wireless terminals in rich isotropic multipath (RIMP) environment as well as in pure line-of-sight (LOS) environment while not ignoring the random positions and orientations of the mobile terminals due to randomness of the user. The latest mobile wireless terminals such as iPhone and iPad can be used in any random position and orientation thereby making the received LOS-component toappear as a random voltage at the antenna ports.
