Abstract
A new automatic frequency control (AFC) algorithm suitable for digital satellite receivers to counter-act large carrier offsets is presented. The proposed two-step scheme uses a low-resolution discrete complex Fourier transform (DFT) for coarse acquisition and a conventional feed forward (FF) estimator for fine tracking. Results from computer simulations are provided to demonstrate the capability of the algorithm
