WiMAX与WCDMA移动通信系统电磁干扰的研究
he Research of Electromagnetic Interference between WiMAX and WCDMA
WiMAX全称是World Interoperability for Microwave Access,是一种宽带无线接入城域网(BWAMAN)技术,亦常称为IEEE Wireless MAN,基本目标是要提供一种城域网区域、点对多点的多厂商环境下可有效互操作的宽带无线接入手段,并且通过论证,其性能可与xDSL、Cable Modem等传统线缆宽带接入手段相媲美,还可保证在一定条件与一定速度移动状态下正常运行。本文首先介绍了WiMAX与WCDMA系统共存时干扰产生原因和各种干扰类型,然后,理论评估了不同场景下两系统基站间干扰大小,并通过计算机仿真给出了不同最小耦合损耗(MCL)、小区半径时的干扰情况。研究结果表明要保证802.16e WiMAX和WCDMA都无损正常工作必须引入一定的隔离保护。最后,本文给出了要保证WCDMA系统正常工作时频率隔离大小建议和相关策略。
WiMAX is an abbreviation of World Interoperability for Microwave Access, a BWAMAN technology which also called IEEE Wireless MAN of Broadband Wireless Access Metropolitan Area Network. Its basic aim is to provide a broadband wireless interoperable access method which adapts to the environment of many operators and single point to multiple points in a metropolitan area.According to argumentation,its performance can be better than conventional lineate technology,such as xDSL,Cable Modem,and operate normally in some conditional moving. In this paper,the section one introduced the types of interference,which existed in the co-existence between WiMAX and WCDMA.Secondly, we quantified the theoretical interference in different scenarios.Also the simulation result demonstrated the condition of several Minmum Coupling-Loss(MCL)and cell radius.The conclusion of the study is the seperation protection is inevitable,this paper provides some strategy and frequency seperation advice.
