TD-SCDMA系统中CPRI协议的研究与应用

Study and Application of CPRI Protocol in TD-SCDMA System

针对中国自主研发的世界三大3G通信系统TD-SCDMA的商用需求,详细介绍了经济简便的通用开放接口标准-CPRI规范以及其在TD-SCDMA系统中的灵活应用,并研究了在TD-SCDMA分布式直放站系统中应用CPRI规范的多样方式。随着TD-SCDMA规模试验网逐渐扩大,对基于CPRI协议的分布式直放站的研究将为其产品节约大量成本,提高通用性和灵活性,并会带来显著的经济效益和社会效益。

TD- SCDMA standard is one of the world＇s three 3G communication systems,which is developed by China independently. For its commercial demands, this paper introduces the CPRI specification,which is an inexpensive and simple common-open-interface standard, and its many kinds of application in TD - SCDMA system. Then some application modes of CPRI specification is studied for distributed repeater of TD- SCDMA system. Because the large - scale testing network of TD - SCDMA is expanding rapidly in China, the research of distributed repeater based on CPRI protocol will save lots of cost for its products, improve its versatility and flexibility, and bring us remarkable economic returns and social benefits.
