1. A demodulator comprising:
a correlator bank including a plurality of correlators, the correlator bank configurable into a plurality of configurations including a signal arrival configuration, a coarse timing configuration, and a despreading configuration, to correlate function transformations of one or more received signals; and
wherein the correlator bank is coupled to receive the function transformations of one or more received signals and template signals corresponding to expected signals.
