Free probability theory as a main branch of random matrix theory is a valuable tool for
describing the asymptotic behavior of multiple systems, especially for those with large …

The classical random matrix theory is mainly focused on asymptotic spectral properties of
random matrices when their dimensions tend to infinity. At the same time, many recent …

In the paper, we consider large-scale multiple-input-multiple-output (MIMO) radar, in which
the numbers of array antennas and snapshots are in the same order of magnitude. Under …
