A novel cyclic algorithm for maximum likelihood frequency estimation
Shaw · 1991
An algorithm for estimation of frequencies of narrowband sources from noisy observation data is presented. For Gaussianly distributed noise, the algorithm produces maximum likelihood estimates, otherwise least-squares estimates, are obtained. The proposed algorithm is iterative, and at each step of iteration the optimization is with respect to a single frequency only, and hence simple hardware/software is sufficient for implementation. The performance of the algorithm has been compared with theoretical Cramer-Rao bounds.>
