Two-Dimensional Frequency-Difference-of-Arrival Varieties

no code implementations25 Mar 2024 Jeanne Duflot, Margaret Cheney, James A. Given

This paper studies Frequency-Difference-of-Arrival (FDOA) curves for the 2-dimensional, 2-sensor case.

On Generalization Bounds for Deep Compound Gaussian Neural Networks

no code implementations20 Feb 2024 Carter Lyons, Raghu G. Raj, Margaret Cheney

In this paper, we develop novel generalization error bounds for a class of unrolled DNNs that are informed by a compound Gaussian prior.

Deep Regularized Compound Gaussian Network for Solving Linear Inverse Problems

1 code implementation28 Nov 2023 Carter Lyons, Raghu G. Raj, Margaret Cheney

Incorporating prior information into inverse problems, e. g. via maximum-a-posteriori estimation, is an important technique for facilitating robust inverse problem solutions.

Compressive Sensing Image Reconstruction

A Compound Gaussian Least Squares Algorithm and Unrolled Network for Linear Inverse Problems

1 code implementation IEEE Transactions on Signal Processing 2023 Carter Lyons, Raghu G. Raj, Margaret Cheney

The first approach is an iterative algorithm that minimizes a regularized least squares objective function where the regularization is based on a compound Gaussian prior distribution.

First-Order Statistical Framework for Multi-Channel Passive Detection

no code implementations14 Feb 2023 Todd McWhorter, Louis Scharf, Margaret Cheney

We consider three types of channel models: 1) the propagation channel is completely known, 2) the propagation is known but channel gains are unknown, and 3) the propagation channel is unknown.
