Abstract
A frame synchronization system and method is disclosed. The system can comprise controller, a search correlator, and a buffer. The controller can be configured to operate on a first stream of first digital sample blocks associated with a first signal and a second stream of second digital sample blocks associated with a second signal. The search correlator can be configured to determine an index of a first unique word (UW) pattern within first searchable digital sample blocks corresponding to the first digital sample blocks and an index of a second UW pattern within second searchable digital sample blocks corresponding to the second digital sample blocks. The buffer can be configured to store the first digital sample blocks and the second digital sample blocks and to release the buffered first and the second digital sample blocks for flow downstream when the stream of first digital sample blocks and the stream of second digital sample blocks are aligned.
