【摘要】 根据接入信道承载的数据类型,提出了在第三代移动通信系统中接入信道的设计要求。通过对WCD MA和CDMA2000接入信道、增强接入信道的分析,比较了两种系统所使用接入技术的优劣。还给出了接入信道仿真程序的设计思路。基于该仿真程序,可以得到两种接入信道的仿真结果,分析得出WCDMA的接入性能要优于CDMA2000的结论。更多还原

【Abstract】 Based on data types beared on the access channel in the third generation mobile communication system,the design demand of access channel is put forward in this paper.The access technology of WCDMA and CDMA2000 systems is compared after analyzed the access channel and reinforced access channel of these two systems.In this paper the design metheds of the simulation program about the access channel are pointed out.Then we can get the result that the access performance of WCDMA is superior to that of CDMA2000 after analyzed the simulation results of the two access channels.Lastly while devising the third generation mobile communication system,we must adjust each parameter of the access channel so as to enlarge system capacity and obtain best capability.更多还原
