Angeliki Alexiou received the Diploma in Electrical and Computer Engineering from the National Technical University of Athens in 1994 and the PhD in Electrical Engineering from Imperial College of Science, Technology and Medicine, University of London in 2000. Since January 1999 she has been a member of technical staff in the Wireless Research Department of Bell Laboratories, Lucent Technologies, Swindon, UK, where she is involved in the development of advanced signal processing techniques for wireless communications. Her current research interests include multiple antenna communications, signal processing for future generation wireless systems, spatio-temporal channel modelling and re-configurable wireless systems supporting adaptivity to varying network conditions. Dr Alexiou is a co-recipient of Bell Labs President’s Gold Award in 2002 for contributions to Bell Labs Layered Space-Time (BLAST) project and the Central Bell Labs Teamwork Award in 2004 for role model teamwork and technical achievements in the IST FITNESS project. Dr Alexiou is the Vice Chair of the Working Group on New Air Interfaces, Relay-based Systems and Smart Antennas of the Wireless World Research Forum. She is a member of the IEEE, the IEE and the Technical Chamber of Greece.
The adoption of Smart Antenna techniques in future wireless systems is expected to have a significant impact on the efficient use of the spectrum, the minimization of the cost of establishing new wireless networks, the optimization of the service quality and the realization of transparent operation across multi-technology wireless networks. Nevertheless, its success relies on the early consideration of the Smart Antenna ‘features’ in the design of future systems (top-down compatibility) and the realistic performance evaluation of Smart Antenna techniques to be performed according to the critical parameters associated with future systems requirements (bottom-up feasibility). In this presentation an overview of the benefits and the most recent advances on Smart Antenna transceiver architectures is given. Then, the most important trends in the adoption of Smart Antennas in future systems are presented, such as re-configurability to varying channel propagation and network conditions, cross layer optimization and multi-user diversity, as well as challenges, such as the design of a suitable simulation methodology and the accurate modeling of channel characteristics, interference and implementation losses.
