Abstract
A new approach for applying the multiple signal classification (MUSIC) method for high spectral resolution signal detection is described. The new approach uses a lower order covariance matrix, or, alternately, an autocorrelation matrix, to calculate only the number of eigenvalues and associated eigenvectors actually needed to solve for the number of signals sought.
