ABSTRACT:
A method and apparatus is provided for synchronizing a received communication signal. A synchronization signal is derived from a received signal having a plurality of synchronization words. Each synchronization word has a predetermined number of synchronization symbols. The synchronization signal is filtered. The filtering is characterized by spacing each filter tap to correspond to synchronization word length increments. Synchronization information is generated which is based on a comparison of the filtered synchronization signal to a threshold. Finally, the synchronization information is output based on a confidence derision derived from the synchronization information.
