| 摘 要： | WCDMA作为3G制式之一,已在中国成功商用.TD - LTE是TD - SCDMA的长期演进,未来也将启用.两种系统在同一地区的共存必将造成两种系统性能的退化.用最小耦合损耗法( MCL,Minimum Coupling Method)对共存的干扰进行了分析,计算出了隔离要求,并给出了能有效降低系统间干扰的天线配置方法.

| Abstract: | WCDMA,one of the 3G standards,is commercially operated in China successfully.TD-LTE,as the evolution of TD-SCDMA,will be operated in the future.Therefore,the two systems may coexist in some area.Accordingly,the inter-system interference caused by coexistence would degrade the performance of both.In this paper,minimum coupling loss(MCL) method is adopted to analyze the coexistence interference.We also calculate the isolation requirements,and investigate the antenna installation method,which can reduce the intersystem interference effectively. |
