Abstract
The frame synchronization words of the preferred embodiment are especially suitable for frame synchronization confirmation. By adding the autocorrelation functions of shaded frame synchronization words, double maximum values equal in magnitude and opposite polarity at zero and middle shifts are obtained. This property can be used to slot-by-slot and double-check frame synchronization timing and reduce the synchronization search time. Further, the present invention allows a simpler construction of a correlator circuit for a receiver.
