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。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 coex- istence interference. We also calculate the isolation requirements, and investigate the antenna installation method, which can reduce the intersystem interference effectively.
