A dynamic multi-path detecting method in CDMA communication system is disclosed, the method includes: A, perform dynamic multi-path difference detection for the multi-path positions gotten from the multi-path detection, judge whether the multi-path position information in the conjoint frames is changed, if it is changed, output all of the multi-path positions that have been done by the multi-path difference detection, and perform the step B, otherwise, treat the multi-path position gotten from the current frame multi-path detection as the final multi-path detection result, and perform the step C; B, perform multi-path validation with every multi-path position that is output, and perform conjoint multi-path process for the multi-path positions that have been validated, treat the multi-path position processed by the conjoint multi-path process as the final multi-path detection result; C, output the final multi-path detection result. The present invention simultaneously discloses a multi-path searcher, it can guarantee the multi-path searching performance and reduce the occurrence of the false alarm in the dynamic channel efficiently through performing the present invention.
