Abstract
A wrap-around event in an automatic frequency control (AFC) in a receiver in a communication system can be detected by performing AFC-like operations on one or more additional channel estimates of the strongest communication path. Once a wrap-around event is detected, a correct frequency reference can be restored by forcing the AFC into a high-speed mode of operation, which gives the AFC a chance to restore the correct frequency reference, or by applying a momentary frequency reference change.
