Title:
DYNAMIC MULTI-PATH DETECTING METHOD AND DEVICE IN CDMA COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2008/122153
Kind Code:
A1
Abstract:
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.
