Subspace selection for projection maximization with matroid constraints
Zhenliang Zhang, Yuan Wang, Edwin K. P. Chong +2
Suppose that there is a ground set which consists of a large number of vectors in a Hilbert space. Consider the problem of selecting a subset of the ground set such that the projec…
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…
