窄带DS-CDMA移动通信的反向链路搜索策略分析及仿真

Analysis and Simulation of Searching Policy of Reverse Link for Narrow Band DS CDMA Cellular System

对窄带ＤＳ－ＣＤＭＡ的反向链路中搜索器的搜索策略进行了分析，提出了搜索窗大小确定的依据，在普通搜索策略基础上，提出一种双搜索窗的新策略，并分析了双积分搜索性能．利用Ｓｙｎｏｐｓｙｓ公司的高级仿真工具ＣＯＳＳＡＰ，对搜索器判决门限进行了仿真确定．

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 method is described and it's performance is analyzed . We do a lot of simulation works in the COSSAP of Synopsys and get some useful results.
