Cramer-Rao Lower Bound Optimization for Hidden Moving Target Sensing via Multi-IRS-Aided Radar
Zahra Esmaeilbeig, Kumar Vijay Mishra, Arian Eamaz +1
Intelligent reflecting surface (IRS) is a rapidly emerging paradigm to enable non-line-of-sight (NLoS) wireless transmission. In this paper, we focus on IRS-aided radar estimation…
Modern GPR Target Recognition Methods
Fabio Giovanneschi, Kumar Vijay Mishra, Maria Antonia Gonzalez-Huici
Traditional GPR target recognition methods include pre-processing the data by removal of noisy signatures, dewowing (high-pass filtering to remove low-frequency noise), filtering,…
Twenty-Five Years of Advances in Beamforming: From Convex and Nonconvex Optimization to Learning Techniques
Ahmet M. Elbir, Kumar Vijay Mishra, Sergiy A. Vorobyov +1
Beamforming is a signal processing technique to steer, shape, and focus an electromagnetic wave using an array of sensors toward a desired direction. It has been used in several en…
Circularly Polarized Fabry-Perot Cavity Sensing Antenna Design using Generative Model
Kainat Yasmeen, Kumar Vijay Mishra, A. V. Subramanyam +1
We consider the problem of designing a circularly polarized Fabry-P'erot cavity (FPC) antenna for S-band sensing applications such as satellite navigation and communication. The sp…
Underwater Acoustic Communication Channel Modeling using Reservoir Computing
Oluwaseyi Onasami, Ming Feng, Hao Xu +2
Underwater acoustic (UWA) communications have been widely used but greatly impaired due to the complicated nature of the underwater environment. In order to improve UWA communicati…
Federated Channel Learning for Intelligent Reflecting Surfaces With Fewer Pilot Signals
Ahmet M. Elbir, Sinem Coleri, Kumar Vijay Mishra
Channel estimation is a critical task in intelligent reflecting surface (IRS)-assisted wireless systems due to the uncertainties imposed by environment dynamics and rapid changes i…
