Ss. Kuzin, AN ESTIMATE OF THE NUMBER OF SOURCES OF INTERFERENCE IN A REVERSING LATTICE FILTER, Telecommunications & radio engineering, 48(4), 1993, pp. 82-85
A method of estimating the number of sources of correlated interferenc
e is proposed by dividing the spectrum of the correlation matrix in a
reversing lattice filter. This enables unbiased estimates to be obtain
ed when one or several of the leading submatrices of the difference co
rrelation matrix is degenerate.
