A MIXED-PATH PROCESSING METHOD IN CDMA SYSTEM

摘要

The technical scheme of a mixed-path processing method in CDMA system is that: when two multi-paths are very close to each other, if the energy of each multi-path is equivalent, they should only slide in opposite direction or keep the current position; if the energy of one multi-path is evidently higher than the other, then the strong one can slide freely, and the weak one can only slide in a deviating direction apart from the strong path. On the basis of said above, a further rule is included in order to enhance the performance, i.e. when the weak multi-path is very close to the strong one and still slides to the strong one, then delete the weak path. If the present method is adopted, it can keep a stable multi-path updating when processing a closer multi-path updating, and can prevent multi-paths sliding to each other, and thus improve the demodulating performance.
