Computationally Efficient Capon- and APES-based Coherence Spectrum Estimation

Abstract
The coherence spectrum is of notable interest as a bivariate spectral measure in a variety of application, and the topic has lately attracted interest with the recent formulation of several ligh-resolution data adaptive estimators. In this work, we further this development with the presentation of computationally efficient implementations of the Caponand APE S-based MSC estimators. The presented implementations furthers the recent development of exploiting the estimators’ inherently low displacement rank of the necessary products of Toeplitz-like matrices to include also the required cross-correlation covariance matrices for the mentioned

coherence algorithms. Numerical simulations together with theoretical
