Cloud K-SVD: A Collaborative Dictionary Learning Algorithm for Big, Distributed Data
Haroon Raja, Waheed U. Bajwa
This paper studies the problem of data-adaptive representations for big, distributed data. It is assumed that a number of geographically-distributed, interconnected sites have mass…
Learning the nonlinear geometry of high-dimensional data: Models and algorithms
Tong Wu, Waheed U. Bajwa
Modern information processing relies on the axiom that high-dimensional data lie near low-dimensional geometric structures. This paper revisits the problem of data-driven learning…
Identification of Linear Time-Varying Systems Through Waveform Diversity
Andrew Harms, Waheed U. Bajwa, Robert Calderbank
Linear, time-varying (LTV) systems composed of time shifts, frequency shifts, and complex amplitude scalings are operators that act on continuous finite-energy waveforms. This pape…
MIMO-MC Radar: A MIMO Radar Approach Based on Matrix Completion
Shunqiao Sun, Waheed U. Bajwa, Athina P. Petropulu
In a typical MIMO radar scenario, transmit nodes transmit orthogonal waveforms, while each receive node performs matched filtering with the known set of transmit waveforms, and for…
A Multiple Hypothesis Testing Approach to Low-Complexity Subspace Unmixing
Waheed U. Bajwa, Dustin G. Mixon
Subspace-based signal processing traditionally focuses on problems involving a few subspaces. Recently, a number of problems in different application areas have emerged that involv…
