走向智能化的第三代移动通信系统

第三代移动通信系统最重要的技术特征是智能移动通信技术，即系统的各功能模块的智能处理单元来实现，这些单元包括智能天线、智能传输、智能接收、智能业务接入和智能网络管理，智能天线的研究最有物色的是适合于ＣＤＭＡ的智能天线技术，智能传输主要涉及延寿适应调制、综合功率控制等；在智能接民中使用中国科技大学提出的最小均方误差简化方法（Ｓ－ＭＭＳＥ）检测的用户数经常规方法的用户数增加约一半，有很好的应用可能；智能

Intelligence - based 3G Mobile Communication System

The third generation mobile communication system features intelligence in the mobile communications technology, which means that the various functional modules of the system are implemented with intelligent processing units. The functional modules include intelligent antennas, intelligent transmission, intellignet reception, intelligent service access and intelligent network management. The unique characteristics of the intelligent antenna research is CDMA - based intelligent antenna technology. The intelligent transmission involves adaptive modulation, integrated power control , etc. For intelligent reception, the simplified minimum mean square error (S -MMSE) method proposed by the Chinese University of Science and Technology is used, providing more than 50 percent increase in number of users. Intelligent reception is managed with intelligent control, providing efficient use of channels and maximum data flow. A supervisory and monitoring method for system multiple access capability and communications capacity is described in this paper.
