摘要
This paper proposes 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 analysis are carried out on the algorithm accuracy, while its performance is compared to the corresponding Cramer-Rao (CR) lower bound.
