ABSTRACT:
A satellite transmission system receiver, for receiving a composite signal including a data component and a synchronization (sync) component is disclosed. The receiver includes a signal processor, responsive to the received data component, and requiring a periodic sync signal in synchronism, with the sync component. A sync signal generator periodically produces the sync signal. A sync component detector, responsive to the sync component, synchronizes the sync signal generator to the received sync component. The satellite transmission system receiver further includes a sync word predictor, responsive to the received data signal, for predicting the locations of sync words in the received data signal and a sync word inserter, coupled to the sync word predictor, for substituting a word having the value of the sync word into the received data signal at a predicted location.
