Danyu Zheng, Zheng Jiang, Yongyu Chang, Dacheng Yang · 2008
In this paper, we study the intercell interference influence on the performance of cell search in TD-SCDMA and propose a new cell search scheme which aims at improving the success probability of the cell search in severe inter-cell interference environment. In our scheme, the multi-cell joint detection (JD) is adopted to reduce the inter-cell interference. The number of cells considered in the multi-cell JD, can be dynamically adjusted in order to reduce the computation complexity. The simulation results reveal that the performance of cell search is considerably improved by this new scheme.
