ABSTRACT:
A system and method for a synchronizing acquisition of a transmitted signal with a local code in a code modulated communication system. The local code is comprised of a replica of the transmitted code. Samples of the transmitted code are correlated with the local code and resulting periodic output samples having indexes are compared with a threshold. Selected indexes of the samples exceeding the threshold are stored and verified for synchronization. Stored correlation indexes which exceed the threshold are combined, and a responder achieves synchronization between transmitted signal and the local code.
