Abstract
A system for acquiring a received spread spectrum signal having a code component, the acquiring including matching the phase of a replica of the code component to the phase of the received code component and also determining a possible shift in the carrier frequency away from a nominal carrier frequency, the acquiring having an intrinsic bandwidth that is substantially the inverse of a predetermined fraction of a code period and also having a design bandwidth that is a fraction of the intrinsic bandwidth including possibly the entire intrinsic bandwidth, the system including means for performing various correlations over sections of a code period, the number of sections determining the intrinsic bandwidth, and adjusting the design bandwidth to be possibly less than the intrinsic bandwidth, so as to alter the characteristics of the acquisition.
