Dr. Sesay is the Head of the Department of Electrical Engineering and Associate Professor at the University of Calgary and an Adjunct Scientist at TRLabs. His research experience has been in the area of (i) modulation, demodulation and receiver optimization, (ii) multiple-access schemes, particularly spread spectrum, (iii) adaptive signal processing, and (iv) application of adaptive signal processing to various wireless communication systems. His work in asymmetric signal processing for indoor wireless radio is being pursued by the cellular radio industry. This approach applies adaptive signal processing to reduce complexity at the portable unit at the expense of the base station in an indoor cellular radio system. Asymmetric strategies are particularly useful in reducing the cost of handheld portables and wireless notebook computers, prolonging battery life and enhancing mobility. Other research activities include wideband modulation schemes which allow high speed (variable rate) data transmission. One approach is based on the use of orthogonal frequency division multiplexing (OFDM). A 150 Mbits/sec indoor wireless LAN has already been prototyped. Also, the theory of spread spectrum is being applied to develop high speed, variable rate (up to 1 Gbits/sec) for indoor data transmission to accommodate multimedia.
