Wimax与TD-SCDMA联合组网中切换技术的研究

The research of the Switching-Mechanism in Investigation network Wimax and TD-SCDMA

本文介绍了目前谈论比较火热的Wimax无线城域网物理层及空中接口关键技术,介绍了在发展和在技术及前景上已经进入成熟阶段的3G标准之一的TD-SCDMA的关键技术。从两者物理层、MAC层的特性,各自的优缺点及市场应用前景等方面对两者进行了分析,讨论了两者技术上的互补性。从底层技术等方面说明两者融合及联合组网的可能。对二者联合组网中的切换技术进行了研究,重点对融合网切换流程进行了探讨并对切换过程中迟滞电平值进行了推导。

The paper introduces the key technology about PHY layer and sky-interface of wireless MAN Wimax and TDSCDMA which is mature in technology prospect and development. Analyses the characters of the PHY and MAC between Wimax and TD-SCDMA. And also contrasts the advantage , disadvantage and market prospect between them. From the basic technology and complementation, the paper discusses the possibility of the two network convergence and priority introduces the Switching-Mechanism of the convergence network.
