Abstract :
A new data-aided frequency estimator for frequency-selective fading channels is introduced. This estimator is developed based on a least squares (LS) error criterion. The proposed method can estimate frequency offsets without the need for channel information. It is shown through simulation that the proposed LS method can be preferred to the existing techniques in mobile communications
