摘　　要：简要概述了国内集群通信系统发展状况,介绍了多基站PDT数字集群通信系统组成与功能,并针对局部大区域、跨区域无线语音通信的实际应用需求,开展了多基站PDT数字集群通信系统设计,并对站址选址覆盖进行了仿真分析和测试。实验证明,该系统能够实现各站点不小于10 km区域的信号覆盖,并且通过网络实现了区域之间的互联,同时预留了扩展接口,可按照后续的需求进一步融合。The development of domestic trunking communication system is given,and the composition and function of PDT digital trunking communication system based on multiple base stations is introduced.To meet the practical application requirements of local large area and cross area wireless voice communication,PDT digital trunking communication system based on multiple base stations is designed.The simulation analysis and the test are also done to solve the problems of site selection and coverage.The experiment proves that in the system,the signal coverage can be no less than 10 kmper station,and the interconnection between areas is also realized through the network.The extension interface is reserved,which can be further integrated according to the subsequent requirements.
