B. Porat et B. Friedlander, ESTIMATION OF FREQUENCY IN THE PRESENCE OF NONRANDOM INTERFERENCE, IEEE transactions on signal processing, 44(3), 1996, pp. 640-651
This paper develops a method of error analysis for Fourier transform-b
ased sinusoidal frequency estimation in the presence of nonrandom inte
rferences. A general error formula is derived and then specialized to
the cases of additive and multiplicative interferences, Approximate er
ror formulas are derived for the case of additive polynomial-phase int
erference. Finally, an application to error analysis in estimating the
parameters of multiple polynomial-phase signals is discussed in detai
l.
