发明名称 CDMA path protection method based on path protection information
摘要 A path protection method for a CDMA reception apparatus is disclosed, which obtains correlation value levels while shifting the despreading timing of reception data little by little, searches for optimal reception timings, outputs a plurality of finger path timings, with respect to the reception data, as reception timings at which reception should be performed, and despreads the respective paths, thereby performing RAKE combining. If all protection paths are in the forward protection state upon execution of path backward protection and forward protection, a protection path with the lowest level is deleted, and a search path having the highest level among paths which are equal to or more than a threshold and detected by a searcher is registered in the deleted portion, thereby allowing assignment of a newly detected path even in the absence of a protection path space.
