Compressive spectral embedding: sidestepping the SVD
Dinesh Ramasamy, Upamanyu Madhow
Spectral embedding based on the Singular Value Decomposition (SVD) is a widely used "preprocessing" step in many learning tasks, typically leading to dimensionality reduction by pr…
Newtonized Orthogonal Matching Pursuit: Frequency Estimation over the Continuum
Babak Mamandipoor, Dinesh Ramasamy, Upamanyu Madhow
We propose a fast sequential algorithm for the fundamental problem of estimating frequencies and amplitudes of a noisy mixture of sinusoids. The algorithm is a natural generalizati…
Compressive channel estimation and tracking for large arrays in mm wave picocells
Zhinus Marzi, Dinesh Ramasamy, Upamanyu Madhow
We propose and investigate a compressive architecture for estimation and tracking of sparse spatial channels in millimeter (mm) wave picocellular networks. The base stations are eq…
A scalable architecture for distributed receive beamforming: analysis and experimental demonstration
Francois Quitin, Andrew T. Irish, Upamanyu Madhow
We propose, analyze and demonstrate an architecture for scalable cooperative reception. In a cluster of N + 1 receive nodes, one node is designated as the final receiver, and the N…
