无线电工程

随着软件无线电技术的兴起,信号处理系统的可移植性和可重用性得到了很大提升。然而,组件化设计不可避免地会增加系统设计复杂度、降低系统运行效率。为了简化组件设计,提高系统开发及运行效率,满足快速搭建原型系统的需求,提出了一种基于服务架构的信号处理系统模型。模型基于ICE中间件技术,解决了Matlab程序快速服务封装和多线程服务调用等关键技术。通过将该架构模型应用于实际的软件无线电系统,验证了其可行性。实验结果表明,该框架具有良好的扩展性,提高了系统性能。

With the rise of the software-defined radio(SDR) technology,the portability and reusability of signal processing system have been improved. However,modular design increases the complexity of system design to reduce the system efficiency. In order to simplify the design of components,improve the efficiency of system development,and rapidly implement prototype system,this paper proposes a model of the signal processing system based on service architecture.Based on ICE,the model solves the Matlab fast service encapsulation and key technology such as multi-threaded service invocation. Through the application of the architecture model to the actual software radio system,its feasibility is verified. The experimental results show that the framework has good expansibility,and improves the performance of the system.
