Minimum Mean-Squared-Error Autocorrelation Processing in Coprime Arrays
Dimitris G. Chachlakis, Tongdi Zhou, Fauzia Ahmad +1
Coprime arrays enable Direction-of-Arrival (DoA) estimation of an increased number of sources. To that end, the receiver estimates the autocorrelation matrix of a larger virtual un…
Structured Autocorrelation Matrix Estimation for Coprime Arrays
Dimitris G. Chachlakis, Panos P. Markopoulos
A coprime array receiver processes a collection of received-signal snapshots to estimate the autocorrelation matrix of a larger (virtual) uniform linear array, known as coarray. By…
L1-norm Tucker Tensor Decomposition
Dimitris G. Chachlakis, Ashley Prater-Bennette, Panos P. Markopoulos
Tucker decomposition is a common method for the analysis of multi-way/tensor data. Standard Tucker has been shown to be sensitive against heavy corruptions, due to its L2-norm-base…
The Exact Solution to Rank-1 L1-norm TUCKER2 Decomposition
Panos P. Markopoulos, Dimitris G. Chachlakis, Evangelos E. Papalexakis
We study rank-1 {L1-norm-based TUCKER2} (L1-TUCKER2) decomposition of 3-way tensors, treated as a collection of matrices that are to be jointly decomposed. Our con…
