摘　　要：MIMO和OFDM技术的有效融合给TD-SCDMA向高性能宽带B3G系统的演进提供了良好的契机。本文首先对3G演进系统的需求进行概述,然后介绍了未来系统空中接口将会采用的一些关键技术,最后提出了TD-SCDMA向未来演进的空中接口解决方案,为实现TD-SCDMA系统的平滑演进提供了可能。The efficient combination of MIMO and OFDM techniques sheds light on the feasibility from TD-SCDMA evolution to high-performance Beyond 3G broadband systems. In this paper, the requirements of evolutional 3G system is first summarized, and then several key technologies for air-interface in future systems are introduced. Finally an air interface candidate for evolutional TD-SCDMA to future is proposed, which gives the possibility of smooth evolution of TD-SCDMA.
