| 摘 要： | 针对TD-SCDMA与WiMAX融合系统,融合过程中下行链路频段出现重叠,存在系统间干扰问题,本文对两者融合中的切换技术进行研究,讨论切换流程、推导切换过程中的迟滞电平,并进行仿真。采用丢包量、时延两个评价指标来衡量系统性能。仿真结果表明,该算法能够较准确地做出切换判决,有效减少了切换次数,消除了"乒乓效应",提高了系统性能。

| Abstract: | By discussing the integration between TD-SCDMA and WiMAX, system interference exists because downlink frequency band over- laps. For the study of the handoff technology in the combined networking, handover procedure is discussed;Hysteresis lever during switching process is deduced. The performance of the system is measured by means of using two evaluating indicator of package and time-delay. The simulation shows that the algorithm can exactly make handoff judgment,reduce the count of handoff efficiently and eliminate the ping-pong effect to improve the performance of the system. |
