讨论了TD-SCDMA系统的优势及特点,并着重阐述了TD-SCDMA系统所应用的联合检测、智能天线、动态信道分配、上行同步技术及接力切换等关键技术。对于标准演进后的核心技术如HSDPA、HSUPA的进展也做了概括性的介绍,并对TD-SCDMA技术的发展方向作了一定的分析。最后简要讨论了TD-SCDMA与WCDMA系统的干扰和共存,回顾了TD-SCDMA发展的成绩,提出了对未来TD-SCDMA产业的展望。
The advantages and features of TD-SCDMA system are discussed. The key technologies such as joint detection, smart antenna, dynamic channel allocation, uplink synchronization and relay switch are also described emphatically. For the standard evolution of the core technologies such as HSDPA, HSUPA progress has also made a general introduction, and the development of TD-SCDMA technology made some analysis. Finally, it briefly discusses the interference and coexistence of TD-SCDMA and WCDMA systems, reviews the achievements of TD-SCDMA development and puts forward the prospect of TD-SCDMA industry in the future.
