Abstract
A method and apparatus for computing a convolution between an input GPS signal and a C/A code reference by generating the convolution result in real time without storing unprocessed signal samples. The method and apparatus is capable of operating in multiple modes of resolution so as to enhance the sensitivity of the convolution processing.
