Abstract
The authors present a new maximum likelihood (ML) frequency estimator for m ultipath channels with sparse impulse response, which is typical for many c ommunications scenarios. The proposed algorithm is based on searching for a maximum in a sum of nonlinear transformed path periodograms. The high accu racy performance of the proposed frequency estimator is demonstrated by sim ulation.
