摘　　要：针对目前中国三大移动运营商3G频谱的分配情况,对时分同步码分多址(TD-SCDMA)与个人手持机系统(PHS)间的干扰作了理论分析和估算,指出完全通过空间隔离方式难以在城市中规避干扰,通过比较天线垂直隔离和加装滤波器两种主要干扰规避方法,得出加装滤波器条件过于苛刻,而天线垂直隔离更易于操作,为目前两个系统的现网共存和发展提供了理论和实践指导。For the situation of 3G frequency allocation for the three operaters in China, the theoretic analysis and estimation of the interference between Time Division Synchronous Code Division Multiple Access（TD-SCDMA） and Personal Handy-phone System（PHS） is done. It is difficult to solve this interference in city by space isolation. The comparison of two interference-avoidance methods, including antenna vertical separation and filtering device, indicates that the antenna vertical separation is more effective than filtering device. This study provides a theoretical practical direction for the coexistence and development of TD-SCDMA and PHS systems.
