Abstract :
The total least squares (TLS) linear prediction (LP) method recently presented by Rahman and Yu (1987) and the equivalent improved Pisarenko´s (IP) method by Kumaresan (1986) are reviewed and generalized by the whitening approach. The resulting whitened-TLS-LP method yields higher estimation accuracy than the TLS-LP. This simulation was carried out in double precision FORTRAN-77 on VAX-8810. The IMSL routines were used to perform eigendecompositions, compute the polynomial roots, and to generate the pseudo-Gaussian random numbers.<>
