Abstract :
A new simple frequency estimator is presented which performs FFT-based coarse and DFT-based dichotomous fine searching of the periodogram peak. The proposed estimator is shown to have a frequency error close to that of the maximum likelihood (ML) estimator and a lower complexity than that of known estimators
