ABSTRACT:
A system acquisition module and corresponding method for facilitating PN code searching which has a PN sequence generator configurable to generate a plurality of PN sequences. The module and method also includes computational units configurable to correlate each received signal sample of a plurality of received signal samples with a corresponding PN sequence of the plurality of PN sequences, and further configurable to provide other hardware resources. A number of computational units from the plurality of computational units are selectively configured to correlate the received signal samples with the PN sequences-the number depending upon availability of the plurality of computational units from providing the other hardware resources. In another embodiment, a communication device having a system acquisition function is provided which includes the system acquisition module and a receiver configured to receive signals, where a plurality of configurable computational units are selectively configurable to implement the PN sequence generator.
