<p>This invention discloses a dynamic multi-path detection method in Code Division Multiple Access communication system, which includes: A Performing dynamic multi-path differential detection on multi-path location obtained from multi-path detection and judging whether multi-path location information on neighboring frame has changed, if so, then output all the multi-path locations after multi-path differential detection, then proceed to step B, otherwise, taking the multi-path location of the current frame after multi-path detection as final multi-path detection result, then proceeding step C; B Performing multi-path verification on each output multi-path location, then performing neighboring multi-path processing on each verified multi-path location, then using multi-path location after neighboring multi-path processing as final multi-path detection result; C Outputting final multi-path detection result. This invention also, in the mean time, discloses a multi-path searcher so that once this invention is adopted, in addition to guaranteeing the performance of multi-path search, the occurrence of false alarm under dynamic channel can be effectively reduced.</p> |
