摘　　要：作为中国提出的国际第三代移动通信标准,TD-SCDMA制式已得到越来越广泛的应用。但现今全球多种通信制式共存,这使得制式间的干扰问题越来越突出,并推动着相关领域的研究。在频段密集分配的现实条件下,杂散干扰很大程度上影响着通信质量。现基于杂散辐射原理,参照各通信制式的标准,对多制式共存中TD-SCDMA受到的杂散干扰进行了定量分析;并用Monte-Carlo方法进行仿真,得出不同干扰源造成的杂散干扰的详细数据。在此基础上通过杂散电平、杂散隔离度等参数来表述干扰状态,为多制式共存时通信平台的建设指标提供有效参考。As one of the international standards of 3G raised by China,TD-SCDMA is applied more widely recently.But under the case of coexistence of several wireless systems,interference among them increasingly affects the system performance,which promotes studies on related areas.Since frequency bands are allocated subtly,spurious emission interference greatly influences the quality of communication.This paper was based on the theory of spurious emission,while interference on TD-SCDMA was quantitatively analyzed referring to standard of each system.The simulation educed detailed data of interference from different systems using Monte-Carlo method.Furthermore,state of interference was described by some parameters such as electronic level and spurious emission isolation,which can be referred in the construction of platform for a number of coexisting systems.
