Revisiting Matching Pursuit: Beyond Approximate Submodularity
We study the problem of selecting a subset of vectors from a large set, to obtain the best signal representation over a family of functions.
D-Band RIS as a Reflect Array: Characterization and Hardware Impairments Study
Reflecting intelligent surface (RIS) has emerged as a promising technology for enhancing wireless communication performance and enabling new applications in 6G networks with potentially low energy consumption and hardware complexity thanks to their passive nature.
Near-Optimal LOS and Orientation Aware Intelligent Reflecting Surface Placement
More specifically, locations, which determine whether BS-IRS and IRS-UE line of sight (LOS) links exist, and surface orientation, which determines whether the BS and UE are within the field of view (FoV) of the surface, play crucial roles in the quality of provided coverage.
Machine Learning-based Methods for Reconfigurable Antenna Mode Selection in MIMO Systems
Due to the non-convexity of this problem, we propose machine learning-based methods for RA antenna mode selection in both dynamic and static scenarios.
Submodularity in Action: From Machine Learning to Signal Processing Applications
We introduce a variety of submodular-friendly applications, and elucidate the relation of submodularity to convexity and concavity which enables efficient optimization.
Compressed-Domain Detection and Estimation for Colocated MIMO Radar
CSP MIMO radar involves two levels of data compression followed by target detection at the compressed domain.
Distributed Resource Allocation Algorithms for Multi-Operator Cognitive Communication Systems
We address the problem of resource allocation (RA) in a cognitive radio (CR) communication system with multiple secondary operators sharing spectrum with an incumbent primary operator.
Decentralizing Multi-Operator Cognitive Radio Resource Allocation: An Asymptotic Analysis
We address the problem of resource allocation (RA) for spectrum underlay in a cognitive radio (CR) communication system with multiple secondary operators sharing resource with an incumbent primary operator.
