UTD Professor, Student Win ‘Best Paper’
Award at International Conference

An electrical engineering professor and a Ph.D. student at The University of Texas at Dallas (UTD) together won the “Best Paper” award at the 2005 Institute of Electrical and Electronics Engineers (IEEE) Vehicular Technology Conference recently held in Dallas.

Dr. Naofal Al–Dhahir, an associate professor, and Sushanta Das are part of the electrical engineering department in UTD’s Erik Jonsson School of Engineering and Computer Science. They are co-authors of the paper with Dr. Robert Calderbank of Princeton University and Dr. Suhas Diggavi of Ecole Polytechnique Fédérale de Lausanne in Switzerland.

 
Sushanta Das, a Ph.D. candidate, and Dr. Naofal Al–Dhahir, an associate professor, are part of the electrical engineering department in UTD’s Erik Jonsson School of Engineering and Computer Science.

More than 570 papers were presented at the conference, which was organized by the IEEE Vehicular Technology Society.

The paper describes a novel transmission scheme for four transmit antennas and investigates its application to broadband wireless access according to the emerging WiMAX industry standard. The authors showed that the proposed scheme results in at least 50 percent increase in the cell coverage area — even under harsh signal propagation conditions — over single-antenna systems with comparable signal decoding complexity.
