Hierarchical Federated Learning for Unsupervised Waveform Classification over Tactical MANETs
Charles E. Thornton, Daniel J. Jakubisin
Distributed radio frequency sensing in contested tactical environments demands collaborative learning across mobile nodes. In ad-hoc networks, learning must occur without persisten…
Hybrid SMI Realization via Matrix Completion and Riemannian Manifold Optimization on Narrowband Sub-Array Based Architectures
Tarun Suman Cousik, Rohit Rangaraj, Nishith Tripathi +3
Hybrid beamforming architectures reduce hardware complexity but restrict access to full array observations, rendering direct implementation of classical covariance based methods su…
Multistatic Radar Performance in the Presence of Distributed Wireless Synchronization
Kumar Sai Bondada, Daniel J. Jakubisin, R. Michael Buehrer
This paper proposes a multistatic radar (MSR) system utilizing a distributed wireless synchronization protocol. The wireless synchronization protocol uses a two-tone waveform excha…
Experimental Demonstration of Robust Distributed Wireless Clock Synchronization
Kumar Sai Bondada, Hiten Kothari, Yibin Liang +2
Distributed wireless clock synchronization is essential for aligning the clocks of distributed transceivers in support of joint transmission and reception techniques. One recently…
Mobile Distributed MIMO (MD-MIMO) for NextG: Mobility Meets Cooperation in Distributed Arrays
Karim A. Said, Yibin Liang, Usama Saeed +13
Distributed multiple-input multiple-output (D\mbox{-}MIMO) is a promising technology to realize the promise of massive MIMO gains by fiber-connecting the distributed antenna arrays…
Distributed Uplink Joint Transmission for 6G Communication
Kumar Sai Bondada, Usama Saeed, Yibin Liang +3
This paper investigates the spectral efficiency achieved through uplink joint transmission, where a serving user and the network users (UEs) collaborate by jointly transmitting to…
