Synchronization acquisition apparatus and method thereof

摘要

A synchronization acquisition apparatus and a method thereof are disclosed. The apparatus includes a local code generator coupled to a plurality of delayers, a plurality of multipliers commonly coupled between the delayers and a plurality of integrators, and a plurality of switches coupled between the multipliers of an integrator. The plurality of integrators are coupled to a detector that detects the maximum integrator output. A plurality of comparators form a feedback loop for obtaining a reliable signal level under any environment and implementing a quick synchronization acquisition without checking all PN code offsets.
