The paper considers the maximum likelihood (ML) estimation of the frequency offset of a known signal received in a multipath channel. The ML algorithm and the Cramer-Rao lower bound are derived. An estimator possessing a low computational load is proposed whose accuracy performance is close to that of the ML estimator over a wide frequency acquisition range
