A General Test for the Linear Structure of Covariance Matrices of Gaussian Populations

ICASSP 2020accepted

This paper addresses the problem of testing whether a covariance matrix can be expressed by an unknown linear combination of a set of known matrices or by another unknown linear combination of a set of different, but known, matrices. This problem is of interest in a wide range of real-world applicat…

Accurate asymptotic analysis for John's test in multichannel signal detection

ICASSP 2016accepted

John's test, which is also known as the locally most invariant test for sphericity of Gaussian variables, is one of the most frequently used methods in multichannel signal detection. The application of John's test requires closed-form and accurate formula to set threshold according to a prescribed f…
