Time Multiplexed Non-Coherent Multipath Search Method and Apparatus
Abstract:
An apparatus for performing a multipath search including a plurality of time-multiplexed chip correlators, wherein each of the plurality of time-multiplexed chip correlators has a pipeline, and further wherein each of the plurality of time-multiplexed chip correlators has a accumulation time is described. A method is described for performing a multipath search including performing multipath search slot processing, determining if a current multipath searching slot is a last multipath searching slot, if the current multipath searching slot is not the last multipath searching slot, then repeating the performing step, if the current multipath searching slot is the last multipath searching slot, then initializing a multipath searching slot index, determining if an non-coherent accumulation has been completed if the accumulation has not been completed then repeating all steps and if the accumulation has been completed, then search results are sorted to locate energy peaks corresponding to multipath locations.
