Abstract

An all-pole Lth order filter with only M (M < Z) nonzero coefficients is used to estimate accurately the frequencies of M closely spaced sinusoidal signals in noise. The method eliminates redundancy in die linear prediction equations which caused the spurious spectral peaks observed in previously known methods [3], [4]. Since most filter coefficients are zero, the computational effort required is small. Copyright © 1982 by The Institute of Electrical and Electronics Engineers, Inc.
