Abstract
In this paper, we introduce robust versions of the recently introduced Capon- and APES-based magnitude square coherence (MSC) spectral estimators. The estimators exploit the related recent development on robust beamforming to allow for imperfect knowledge of the estimated sample correlation matrix. The resulting estimators are found to yield improved estimates as compared to the earlier estimators.
