Underwater Acoustic Communications: Channel Modeling


In this lecture, we address the fundamentals of acoustic propagation, as well as the more intricate details of statistical channel modeling that addresses random effects such as location uncertainty, environmental conditions, scattering and motion-induced Doppler scaling. We develop a mathematical model for the channel response, taking into account the effects of multipath propagation as well as time variation. We distinguish between deterministic and random features of the channel, and further classify the latter into those that occur on large and small scales. The resulting statistical characterization includes both the probability density functions and the correlation functions of salient channel parameters, yielding numerical channel models that can be used for simulation, as well as theoretical analyses of the average bit error rate, outage probability, percent coverage, and similar statistical measures that quantify the performance of an underwater acoustic communication system.


Milica Stojanovic graduated from the University of Belgrade, Serbia, in 1988, and received the M.S. and Ph.D. degrees in electrical engineering from Northeastern University in Boston, in 1991 and 1993, respectively. She was a Principal Scientist at the Massachusetts Institute of Technology, and in 2008 joined Northeastern University, where she is currently a Professor of Electrical and Computer Engineering. She is also a Guest Investigator at the Woods Hole Oceanographic Institution. Her research interests include digital communications theory, statistical signal processing and wireless networks, and their applications to underwater acoustic systems. Milica is a Fellow of the IEEE, an Associate Editor for the IEEE Journal of Oceanic Engineering, and the Chair of the IEEE Ocean Engineering Society’s Technical Committee for Underwater Communication, Navigation and Positioning. She also serves on the Editorial Board of the IEEE Signal Processing Magazine and has in past served on board the IEEE Communication Letters, IEEE Transactions on Signal Processing, and IEEE Transactions on Vehicular Technology. Milica is the recipient of the 2015 IEEE/OES Distinguished Technical Achievement Award, and the 2019 IEEE WICE Outstanding Achievement Award.
