Improved Fast Cell Search Algorithm for DS-CDMA Mobile Radio System employing Asynchronous Inter-cell
Yong Seo Park, Mun Gyu Song, Yeong Ji Jeong · 1999
In the DS-CDMA based cellular radio system, asynchronous inter-cell operation which assigns the unique code to each cell can be realized cells. But generally it takes much more time for cell search than syncnronous inter-cell option. In this paper the improved fast cell search algorithm to be able to succeed search cell faster than conventional one was proposed and simulated by computer. The pipeline principle was applied to the proposed algorithm through cell search process. In the case of failure of cell search, the cell search processes restart instead of returning to the first step of cell search processes by updating the signals for cell seaech at the point of its failure. Simulation results show that the proposed algorithm could apparently reduce the cell search time.
