ABSTRACT:
A Kronecker product code structure for a synchronization word is presented which permits the use of dual-mode sequential matched filter. This matched filter permits a large reduction in acquisition time since the number of frequency bins that must be searched is greatly reduced when there is a large frequency uncertainty. In the first mode of operation the output of a filter matched to the high rate code is non-coherently integrated in a post-detection integrator to obtain reliable but ambiguous acquisition of the synchronization word. In the second mode of operation the ambiguity is resolved.
