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…
Scalable and Efficient Geographic Routing in Mobile Ad Hoc Wireless Networks
Dinesh Ramasamy, Upamanyu Madhow
We propose and evaluate a scalable position-publish and an accompanying routing protocol which is efficient despite operating with imperfect information regarding the destination's…
Compressive parameter estimation in AWGN
Dinesh Ramasamy, Sriram Venkateswaran, Upamanyu Madhow
Compressed sensing is by now well-established as an effective tool for extracting sparsely distributed information, where sparsity is a discrete concept, referring to the number of…
