摘　　要：传统发射机更多地依赖于硬件,可扩展性差,很难满足复杂多变的应用环境。软件无线电发射机可以通过重配置应用软件来满足不同环境和用户的需求,具有很大灵活性。文中阐述基频发射机的关键技术及实现模型进行,利用基于TMS320C6713的DSP集成开发环境CCS进行仿真设计,该仿真结果对构建软件无线电发射机颇具理论和实践指导意义。The traditional radio transmitter relies mostly on hardware, whose expansibihty is poor, and it is very difficult to meet the complex and changeable application environment. The SR（ software radio） transmitter can meet different environment and demands of the users through the reshuffle application software, thus having very big flexibihty. This paper elaborates the key technologies and realization models of baseband transmitter, and carried out the design and simulation based on TMS320C6713 DSP integrated development environment CCS. The simulation results provide theoretical guidance in constructing a SR transmitter.
