Threshold Effects in Parameter Estimation from Compressed Data
Pooria Pakrooh, Louis L. Scharf, Ali Pezeshki
In this paper, we investigate threshold effects associated with swapping of signal and noise subspaces in estimating signal parameters from compressed noisy data. The term threshol…
Modal Analysis Using Sparse and Co-prime Arrays
Pooria Pakrooh, Louis L. Scharf, Ali Pezeshki
Let a measurement consist of a linear combination of damped complex exponential modes, plus noise. The problem is to estimate the parameters of these modes, as in line spectrum est…
The Geometry of Fusion Inspired Channel Design
Yuan Wang, Haonan Wang, Louis Scharf
This paper is motivated by the problem of integrating multiple sources of measurements. We consider two multiple-input-multiple-output (MIMO) channels, a primary channel and a seco…
Greedy Adaptive Compression in Signal-Plus-Noise Models
Entao Liu, Edwin K. P. Chong, Louis L. Scharf
The purpose of this article is to examine the greedy adaptive measurement policy in the context of a linear Guassian measurement model with an optimization criterion based on infor…
