Zusammenfassung:In order to increase the OFDM cell identification numbers as well as remain the cell search performance, a new scheme was proposed. The core idea is that the 'sub-carrier mask index' is loaded before differential sequence is modulated on the sub-carrier. A jointly estimating algorithm is designed to improve the performance so the proposed scheme can identify 10 to 20 times the call identification numbers of the traditional scheme.
