2-D DOA and mutual coupling coefficient estimation for arbitrary array structures with single and multiple snapshots

TL;DR: In this paper, the joint-sparsity of the array model is exploited to estimate both DOA and MC coefficients with a single snapshot for an unstructured array where the antennas are placed arbitrarily in space.

Localization of multiple disjoint sources with prior knowledge on source locations in the presence of sensor location errors

TL;DR: The problem of localizing multiple disjoint sources where prior knowledge on the source locations is available to mitigate the effect of sensor location uncertainty is considered and the Cramer-Rao lower bound (CRLB) is derived.

Compressive-Sampling-Based Positioning in Wireless Body Area Networks

TL;DR: A new modeling and analysis framework for the multipatient positioning in a wireless body area network (WBAN) which exploits the spatial sparsity of patients and a sparse fast Fourier transform (FFT)-based feature extraction mechanism for monitoring of Patients and for reporting the movement tracking to a central database server containing patient vital information is presented.

Compressed sensing

TL;DR: It is possible to design n=O(Nlog(m)) nonadaptive measurements allowing reconstruction with accuracy comparable to that attainable with direct knowledge of the N most important coefficients, and a good approximation to those N important coefficients is extracted from the n measurements by solving a linear program-Basis Pursuit in signal processing.

An Introduction To Compressive Sampling

TL;DR: The theory of compressive sampling, also known as compressed sensing or CS, is surveyed, a novel sensing/sampling paradigm that goes against the common wisdom in data acquisition.

Content-based classification, search, and retrieval of audio

TL;DR: The audio analysis, search, and classification engine described here reduces sounds to perceptual and acoustical features, which lets users search or retrieve sounds by any one feature or a combination of them, by specifying previously learned classes based on these features.

Signal Processing With Compressive Measurements

TL;DR: This paper takes some first steps in the direction of solving inference problems-such as detection, classification, or estimation-and filtering problems using only compressive measurements and without ever reconstructing the signals involved.

Distributed target localization via spatial sparsity

TL;DR: It is shown that the proposed approximation framework can successfully determine multiple target locations by using linear dimensionality-reducing projections of sensor measurements, ameliorating the communication requirements.
