Abstract
A neu automatic frequency control (AFC) algorithm suitable for digital sate llite receivers to counteract large carrier offsets is presented. The propo sed two-step scheme uses a low-resolution discrete complex Fourier transfor m (DFT) for coarse acquisition. and a conventional feed forward (FF) estima tor for fine tracking. Results from computer simulations are provided to de monstrate the capability of the algorithm.
