摘　　要：集群系统的呼叫业务大部分采用单点对多点的半双工通信方式,与TD-SCDMA系统普通呼叫的通信方式不同。文中研究和分析了TD-SCDMA集群通信系统中所存在的干扰,建立了干扰模型,阐述了各种干扰产生的过程和原因,并对其交叉时隙干扰进行了仿真和比较。仿真结果表明TD-SCDMA集群系统的交叉时隙干扰要比TD-SCDMA系统更加严重。In trunking communication systems, unlike the traditional call in TD-SCDMA system, most calls take the communication mode of point to muhipoint half-duplex mode. Firstly study and analysis are con- ducted and a model is established for the interference in the TD-SCDMA trunking system. Then the process and causes of the interference are described. Finally, simulation and comparison are made on the cross-slot interference. The simulation results have shown that the cross-slot interference in TD-SCDMA trunking system is stronger than that in TD-SCDMA system.
