The authors propose in this paper a frequency-based least squares algorithm applied to the estimation of multifrequency signal parameters. It is based on the processing of the joint information carried by nearby frequency components of Fourier-transformed data. Theoretical and simulated analyses are carried out on the algorithm accuracy, while its performance is compared to the corresponding Cramer-Rao lower bounds
