Abstract
An apparatus, system, and corresponding method for acquiring a spread spectrum signal, where the acquiring includes matching the phase of a replica of a code component to the phase of the received code component and also determining the carrier frequency including any Doppler or other shifting, the apparatus including: a multi-section matched filter for providing successive section outputs each including elements corresponding to a different replica code phase; and a compensated acquisition module, responsive to each section output of each of the sections, for providing a sequence of frequency indicators, each corresponding to a different frequency offset, with each section output having elements each of which corresponds to a particular value of replica code phase, wherein each frequency indicator is based on a combining, phase element-wise, of the section outputs using compensating factors that depend on the corresponding frequency offset.
