P. Stoica et al., ON A NONPARAMETRIC DETECTION METHOD FOR ARRAY SIGNAL-PROCESSING IN CORRELATED NOISE FIELDS, IEEE transactions on signal processing, 44(4), 1996, pp. 1030-1032
The correct derivation of maximization of the likelihood function is p
resented, and the correct form of information theoretic criteria (ITC)
for the determination of the number of signals in an unknown correlat
ed noise field is shown. The possible pitfalls of using ITC under the
circumstances are briefly considered.
