Minimum Mean-Squared-Error Autocorrelation Processing in Coprime Arrays

no code implementations21 Oct 2020 Dimitris G. Chachlakis, Tongdi Zhou, Fauzia Ahmad, Panos P. Markopoulos

Coprime arrays enable Direction-of-Arrival (DoA) estimation of an increased number of sources.

Structured Autocorrelation Matrix Estimation for Coprime Arrays

no code implementations27 Aug 2020 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.

The Exact Solution to Rank-1 L1-norm TUCKER2 Decomposition

1 code implementation31 Oct 2017 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 $N$ $D \times M$ matrices that are to be jointly decomposed.
