The adaptive coherence estimator is the generalized likelihood ratio test for a class of heterogeneous environments [PDF]
, 2008 The adaptive coherence estimator (ACE) is known to be the generalized likelihood ratio test (GLRT) in partially homogeneous environments, i.e., when the covariance matrix Ms of the secondary data is proportional to the covariance matrix Mp of the vector ...
