Sampling and Recovery of Signals on a Simplicial Complex using Neighbourhood Aggregation
Siddartha Reddy, Sundeep Prabhakar Chepuri
In this work, we focus on sampling and recovery of signals over simplicial complexes. In particular, we subsample a simplicial signal of a certain order and focus on recovering mul…
Coded Aperture Radar Imaging Using Reconfigurable Intelligent Surfaces
R. S. Prasobh Sankar, Sundeep Prabhakar Chepuri
In this paper, we focus on radar imaging using active sensing with a single transceiver and reconfigurable intelligent surface (RIS). RISs are arrays with tunable passive phase shi…
Clustering with Simplicial Complexes
Thummaluru Siddartha Reddy, Sundeep Prabhakar Chepuri, Pierre Borgnat
In this work, we propose a new clustering algorithm to group nodes in networks based on second-order simplices (aka filled triangles) to leverage higher-order network interactions.…
Learning to Precode for Integrated Sensing and Communications Systems
R. S. Prasobh Sankar, Sidharth S. Nair, Siddhant Doshi +1
In this paper, we present an unsupervised learning neural model to design transmit precoders for integrated sensing and communication (ISAC) systems to maximize the worst-case targ…
Optimal Placement of Active and Passive Elements in Hybrid RIS-assisted Communication Systems
R. S. Prasobh Sankar, Sundeep Prabhakar Chepuri
Hybrid reconfigurable intelligent surfaces (HRIS) are RIS architectures having both active and passive elements. The received signal-to-noise ratio (SNR) in HRIS-assisted communica…
