Abstract
The authors propose a technique for adaptive spectral estimation that is based on the method of conjugate gradient and is used for iteratively finding the eigenvector corresponding to the minimum eigenvalue of the covariance matrix. The new method is an exact adaptive version of V. F. Pisarenko's method (1973) and converges in finite steps for any initial guesses. Simulations show that the new method improves CPU time by a factor of 40. The technique performs very well for both narrowband and wideband signals.
