摘　　要：介绍一种基于软件无线电的卫星通信模拟源。提出基于FPGA和高速D/A转换器的硬件系统的实现方法和设计注意事项。描述了软件系统中各模块的基本原理和功能,并根据软件无线电基本理论给出了它们的具体实现,同时给出模拟源输出信号的EVM测试结果。该系统硬件组成简单,输出信号的调制方式和数据协议可任意切换,通用性和扩展性强。A simulation source based on software radio for satellite communication is introduced, The implementation method and design notes of the hardware system based on FPGA and high-speed D/A converter are put forward. The basic principle and function of the modules of the software system are depicted. The realization based on software radio theory and the EVM testing results of the output signal of the simulation source are presented. The structure of the system is very simple, and the modulation mode and data protocols can be switched over arbitrarily, so it has the general universality and strong expansibility.
