摘要
介绍了WiMAX的无线城域网物理层和空中接口技术,以及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 key technologies of PHY layer and air interface in WiMAX wireless MAN and in TD-SCDMA, compares the PHY and MAC characteristics of WiMAX and TD-SCDMA, and analyzes their advantages, disadvantages and market prospects. By discussing the complementarity between WiMAX and TD- SCDMA, the paper points out the possibility of the convergence and combined networking of the two technologies. Furthermore, the paper studied the handoff technology in combined networking.
