Abstract
Recently, inter-cell asynchronous DS-CDMA systems were proposed for third-generation mobile systems, and many researches on this system are in progress. In [1], an inter-cell asynchronous mode DS-CDMA system using two pilot structure was proposed for flexible cell deployment. In the system, a cell site transmits two pilots of cluster and cell pilot, and the cell search is performed by two steps to decrease cell search time. In this paper, a practical cell structure and cell search algorithm based on the two pilot scheme of [1] are described, and the performance of the cell search algorithm is evaluated by computer simulations. The results shows that over than 90% of cell search can be completed within about 600 ms when 512 cell pilot codes of 40960 chip length is used.
