【摘要】 TD-SCDMA是我国自己研究和发展的产业,它在中国乃至国际的通信业上都有着重要的地位。TD-SCDMA系统采用了一系列关键技术,包括:智能天线、联合检测、上行同步控制、动态信道分配、N频点小区、接力切换和无线链路监测等等。这些关键技术的采用使TD-SCDMA系统的网络性能得到了很大的提高。本论文首先介绍了TD-SCDMA系统的概要和整体优势,然后详细阐述系统中的三个关键技术——智能天线、联合检测和接力切换的实现原理,具体研究了智能天线、联合检测和接力切换对TD-SCDMA系统干扰的影响,对系统容量的影响等。作者在本公司TD-SCDMA项目小组的工作,参加一些网络规划和路测试验,再通过比较这三种关键技术与别的技术的区别、一系列的仿真和测试项目等证实它们在TD-SCDMA系统中的优势,如减少系统的干扰、增加系统的容量、降低系统的掉话率等。在论文中强调了结合使用这几种关键技术的优点和重要性。更多还原

【Abstract】 The system of TD-SCDMA is developed by China, so it has the important pole in the Chinese telecommunication field, even in the international telecommunication field. TD-SCDMA adopts several key techniques including Smart Antenna, Joint Detect, Uplink Synchronization Control, Dynamic Channel Allocation, N-frequency sector, Baton handover and Radio-link detect which can improve the network performance of TD-SCDMA.In this paper, to introduce the summary and advantages of TD-SCDMA, the theory of three key techniques such as Smart Antenna, Joint Detect and Baton handover. And to study the interference influence and the capability influence of Smart Antenna, Joint Detect and Baton handover on the TD-SCDMA. Author takes part in the jobs of network planning and road-mapping in the company. Though comparing the three key techniques with the other techniques and a series of simulators and tests, the advantages of the key techniques are validated, such as reducing the system’s interference, increasing the system’s capability, decreasing the call-failure rate and so on. In the paper, also to emphasize the importance and advantages of combining the three key techniques.更多还原
