Signal Recovery From Unlabeled Samples [PDF]

open access: yesIEEE Transactions on Signal Processing, 2017
In this paper, we study the recovery of a signal from a set of noisy linear projections (measurements), when such projections are unlabeled, that is, the correspondence between the measurements and the set of projection vectors (i.e., the rows of the measurement matrix) is not known a priori.

Stable signal recovery from incomplete and inaccurate measurements [PDF]

open access: yes, 2005
Suppose we wish to recover a vector x0 ∈ ℝ𝓂 (e.g., a digital signal or image) from incomplete and contaminated observations y = A x0 + e; A is an 𝓃 Γ— 𝓂 matrix with far fewer rows than columns (𝓃 β‰ͺ 𝓂) and e is an error term.

Signal Recovery on Incoherent Manifolds [PDF]

open access: yesIEEE Transactions on Information Theory, 2012
Suppose that we observe noisy linear measurements of an unknown signal that can be modeled as the sum of two component signals, each of which arises from a nonlinear sub-manifold of a high dimensional ambient space. We introduce SPIN, a first order projected gradient method to recover the signal components.

Jointly Sparse Signal Recovery and Support Recovery via Deep Learning With Applications in MIMO-Based Grant-Free Random Access [PDF]

open access: yesIEEE Journal on Selected Areas in Communications, 2020
In this article, we investigate jointly sparse signal recovery and jointly sparse support recovery in Multiple Measurement Vector (MMV) models for complex signals, which arise in many applications in communications and signal processing.

Learning Sampling and Model-Based Signal Recovery for Compressed Sensing MRI [PDF]

open access: yesIEEE International Conference on Acoustics, Speech, and Signal Processing, 2020
Compressed sensing (CS) MRI relies on adequate under-sampling of the k-space to accelerate the acquisition without compromising image quality. Consequently, the design of optimal sampling patterns for these k-space coefficients has received significant ...

Effects of Optical Sampling Pulse Power, RF Power, and Electronic Back-End Bandwidth on the Performance of Photonic Analog-to-Digital Converter

open access: yesMicromachines, 2023
The effects of optical sampling pulse power, RF power, and electronic back-end bandwidth on the performance of time- and wavelength-interleaved photonic analog-to-digital converter (PADC) with eight-channel 41.6 GHz pulses have been experimentally ...

Consistent Sampling and Signal Recovery [PDF]

open access: yesIEEE Transactions on Signal Processing, 2007
An attractive formulation of the sampling problem is based on the principle of a consistent signal reconstruction. The requirement is that the reconstructed signal is indistinguishable from the input in the sense that it yields the exact same measurements. Such a system can be interpreted as an oblique projection onto a given reconstruction space.

Newton-Step-Based Hard Thresholding Algorithms for Sparse Signal Recovery [PDF]

open access: yesIEEE Transactions on Signal Processing, 2020
Sparse signal recovery or compressed sensing can be formulated as certain sparse optimization problems. The classic optimization theory indicates that the Newton-like method often has a numerical advantage over the classic gradient method for nonlinear ...
