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…
Analysis of Fisher Information and the Cramér-Rao Bound for Nonlinear Parameter Estimation after Compressed Sensing
Pooria Pakrooh, Ali Pezeshki, Louis L. Scharf +2
In this paper, we analyze the impact of compressed sensing with complex random matrices on Fisher information and the Cramér-Rao Bound (CRB) for estimating unknown parameters in th…
OFDM pilot allocation for sparse channel estimation
Pooria Pakrooh, Arash Amini, Farrokh Marvasti
In communication systems, efficient use of the spectrum is an indispensable concern. Recently the use of compressed sensing for the purpose of estimating Orthogonal Frequency Divis…
