摘要
第三代移动通信系统目标主要是全球化、综合化和个人化,其主流制式有三种:欧洲和日本共同提出的WCDMA-FDD/TDD、以美国高通北美公司为主导提出的cdma2000和以中国大唐为代表提出的TD-SCDMA。3G系统为用户提供了多种新型特色业务,将成为移动通信的新一代技术标准,但同样也面临多径衰落等几点主要问题。伴随着TD-SCDMA终端芯片领域的群体突破,我国TD-SCDMA终端产品的研发及产业化工作已经步入了快车道,商业化应用也正式起航。
The aim of the 3G Mobile-Network outlines as: Globalization, Integration and Personalization. And the mainstream m structures are three: The WCDMA-FDD/TDD generalized by Europe and Japan, the CDMA2000 featured by Go Tone America and the TD-SCDMA at the name of DaTang China.3G system provides users with new multi-services, becoming the new one technique standard of Mobile-Phone communication. Some problems, however, are also faced, like multipath-fading. Accompanying the group-change of the field of TD-SCDMA Terminal chop, in china, the experiments and production of TD-SCDMA Terminals have on express presently, and so does commercial Applications.
