The holistic approach to wireless network agility and optimally controlled wireless spectrum co-existence calls for joint treatment of the space-time-frequency continuum and the design of carrier waveforms (signatures) that utilize the entire continuum of the readable frequency spectrum (all-spectrum approach). Such treatment translates to all-spectrum agile waveform design in space that is repeatedly optimized in time with speed that is commensurate with the coherence time of the varying network dynamics and environmental conditions. In this talk, I will discuss principled algorithms for all-spectrum waveform optimization where individual transceiver pairs autonomously optimize coded-repeats of one or more basic pulses over different finite alphabets. This approach provides the waveform fabric (signature) on which we can carry information symbols with any desirable level of interference avoidance allowed by the physics of the medium and our hardware limitations. The effectiveness of the all-spectrum approach is illustrated using narrowband and wideband transceiver pairs and challenging ad-hoc network deployments of software-defined radios in a controlled contested environment.

Biography:

George Sklivanitis is the Schmidt Research Assistant Professor of Electrical Engineering and Computer Science, a faculty fellow with the Institute for Sensing and Embedded Network Systems Engineering (I-SENSE) and a founding member of the Center for Connected Autonomy and Artificial Intelligence (CA-AI) at Florida Atlantic University (FAU). Prior to joining FAU, Dr. Sklivanitis received his Ph.D. degree in Electrical Engineering from the State University of New York at Buffalo, NY, USA in 2018. His research focuses on modeling, optimization and experimental evaluation of autonomous networked AI systems in challenging, congested (and sometimes contested) communication environments such as underwater, in the sky and in space. He has more than 30 publications in predominantly IEEE venues and in 2014 he ranked 1st among all U.S. Universities in the Nutaq Software-defined Radio Academic US National Contest. In 2021, he was recognized by the Economist as one of the three winners of the World Ocean Initiative's Ocean Changemakers Challenge. In 2017, he co-founded the IEEE Workshop on Wireless Communications and Networking in Extreme Environments (WCNEE). Dr. Sklivanitis has won several teaching, research and entrepreneurial awards, including: Best Paper Award Finalist in the 15th IEEE International Workshop on Antenna Technology (iWAT-2019); 2017 SUNY Chancellor’s Award; Best Demo Award in the 10th ACM International Conference on Underwater Networks and Systems (WUWNet-2015); and 2015 SUNY Buffalo Graduate Student Award for Excellence in Teaching.
