ABSTRACT:
A method of increasing speed of digital correlation processing in a global positioning system (GPS) receiver and associated receiver. The method comprises steps of digitizing a received GPS signal at a first rate to obtain digitized samples, storing the digitized samples in a memory at the first rate, reading packs of a predetermined number of digitized samples at a second rate that is faster than the first rate, generating packs of the predetermined number of signal replica samples at the second rate, and correlating the packs of digitized samples from the memory with the generated replica samples at the second rate.
