3GPP W-CDMA에서 개선된 초기 셀 탐색 알고리즘

In this paper, the improved initial cell searching algorithm is proposed for 3GPP W-CDMA system. The key objective of the proposed algorithm is to utilize the reliability of the first stage of cell searching algorithm in order to accomplish the second stage. So the proposed algorithm makes the mobile station transfers to the second stage from the first stage, just after the slot synchronization is declared successively at the same time-offset. In order to compare the proposed algorithm with the conventional one, the simulations are accomplished for cell search algorithm for 3GPP W-CDMA systems in the multipath Rayleigh fading channel. Some parameters are also presented for the better performance in the initial cell searching algorithm.
