摘　　要：分析时分同步码分多址(TD-SCDMA)体制同步轨道卫星通信系统受到的多址干扰,并给出上/下行链路单小区单时隙容量的理论分析。建立TD-SCDMA卫星通信系统的干扰仿真模型,分析影响上/下行容量的因素,为兼容TD-SCDMA的卫星通信系统的规划设计提供参考。This paper analyzes the multiple access interference suffered by TD-SCDMA(Time Division Synchronous CDMA) geosynchronous satellite communication systems,and derives the uplink/downlink slot capacity for the single cell of TD-SCDMA systems.An interference model for the TD-SCDMA satellite communication is developed to analyze the factors limiting the system capacity.The paper can be a reference for the design of TD-SCDMA compatible GEO satellite communication system.
