Abstract: The searching policy of reverse link in narrowband DS-CDMA was analyzed. The method to determine the size of searching window and the double searching window policy were presented . Double length searching methodis described and it's performance is analyzed . We do a lot of simulation worksin the COSSAP of Synopsys and get some useful results.

Key words: CDMA, acquisition, searching window, simulation
