Abstract
A method for increasing signal acquisition in global positioning system receivers is described. An algorithm for a banked filter of the invention provides low attenuation between frequency bins in which all of the frequency bins produce useful results and no multiplications are required to implement the algorithm. A shortened sampling interval is provided and a banked filter process is implemented. The multiple outputs of the banked filter are detected and summed in post detection filters.
