Diffusion model for gradient preconditioning in hyperspectral imaging inverse problems
Jonathan Monsalve, Kumar Vijay Mishra
Recovering high-dimensional statistical structure from limited measurements is a fundamental challenge in hyperspectral imaging, where capturing full-resolution data is often infea…
Coherent Source Enumeration with Compact ULAs
Dibakar Sil, Sunder Ram Krishnan, Kumar Vijay Mishra
Source enumeration typically relies on subspace-based techniques that require accurate separation of signal and noise subspaces. However, prior works do not address coherent source…
CLuP-Based Dual-Deconvolution in Automotive ISAC Scenarios
Jonathan Monsalve, Kumar Vijay Mishra
Accurate target parameter estimation of range, velocity, and angle is essential for vehicle safety in advanced driver assistance systems (ADAS) and autonomous vehicles. To enable s…
Deep Learning Model-Based Channel Estimation for THz Band Massive MIMO with RF Impairments
Pulok Tarafder, Imtiaz Ahmed, Danda B. Rawat +2
THz band enabled large scale massive MIMO (M-MIMO) is considered as a key enabler for the 6G technology, given its enormous bandwidth and for its low latency connectivity. In the l…
Sub-Nyquist Radar: Principles and Prototypes
Kumar Vijay Mishra, Yonina C. Eldar
In the past few years, new approaches to radar signal processing have been introduced which allow the radar to perform signal detection and parameter estimation from much fewer mea…
