| Abstract(in English) | Fast cell search scheme in idle mode of mobile station is proposed for W-CDMA asynhonous cellular system. In the proposed scheme the base station which was connected to the mobile station infroms the mobile station, the reative differences of scrambling codes phase and the indexes of relative scrambing codes for all neighbor base stations to be searched. The mobile station in idle mode can limit the relative screambling code phases that should be searched. Therefore, the cell search time in asynchronous system is almost the same as that in synchonous system. It was demonstrated from computer simulations that cell search can be accomplished in less than 12.5ms at 95% of the locations when the number of averaging symbols is 4, the number of sliding correlators is 4 and the windouw size is 10chips. It is also shown that about 95% of the location can be achieved at 1.7% of activity. |
