摘　　要：第三代移动通信系统的无线接口国际标准即将形成,在提交ITU的10个技术提案中,最具竞争力的是W-CDMA和cdma2000.这两种宽带CDMA方案除了码片速率、同步方式和导频方式等有所不同外,功率控制和软切换等基本技术和性能都没什么差别.两者有可能相互融合,主要障碍在知识产权以及与第二代系统后向兼容等利益问题上.中国提交的TD-SCDMA技术与欧洲的TD-CDMA很类似,正积极探讨融合成一种方案的可能性.中国应积极支持标准统一,加强相关的标准化研究和技术开发工作.This paper describes the current development of the third generation mobile telecommunications in the world. In particular, two wideband CDMA proposals are described and compared and the current harmonization status is also presented in this paper. The characteristics of Chinese proposal TD-SCDMA are described and the convergence with other TDD proposal is also given here. Finally, some personal advice on IMT-2000 related research and development are given in this paper.
