PROGRAMMABLE MATCHED FILTER SEARCHER FOR MULTIPLE PILOT SEARCHING |
摘要 |
A novel and improved method and apparatus for searching is described. This searcher combines the ability to search multiple offsets of single pilots, such as those found in the IS-95 system, with the ability to search multiple pilots, such as those found in a GPS location determination system. Both typ es of searching can be done in a single architecture combining the parallel computation features of a matched filter with the flexibility of allowing a variable number of non-coherant accumulations to be performed at high speed for a wide range of search hypotheses in a resource efficient manner. This invention allows for parallel use of the matched filter structure in a time- sliced manner to search multiple windows. In addition, the searcher allows f or optional independent Walsh decovering for each search window. The time-shari ng approach allows for optional frequency searching of any offset.
