John Fonseka is a Professor of Electrical Engineering at the University of Texas at Dallas (UT Dallas), affiliated with the Erik Jonsson School of Engineering and Computer Science. He holds a Ph.D. in Electrical Engineering from Arizona State University (1988), an M.Eng. from Memorial University of Newfoundland (1985), and a B.Sc. from the University of Moratuwa, Sri Lanka (1980). His research focuses on communication theory , particularly in modulation and coding , with emphasis on bandwidth-efficient techniques and throughput enhancement. Key areas include coded modulation, error control coding, channel capacity calculations, and transmission over fading channels. He has explored topics such as quadrature multiplexed CPM, trellis-coded modulation with adaptive constellations, and capacity analysis in Nakagami- and Rician-fading environments. Notable contributions include work on CPFSK error reduction, noncoherent detection strategies, and OFDM applications. His publications span IET Communications , IEEE Transactions on Communications , and Electronics Letters , reflecting expertise in both theoretical and applied signal processing. Fonseka’s academic profile reflects over three decades of contributions to reliable communication systems, with a focus on optimizing performance in challenging channel conditions.
