摘要：

随着通信体制的日益发展,对应的解调算法也呈现多样化的形态。结合软件无线电技术的应用,研究高效、快捷的解调器开发方式显得越来越重要。文中利用软件无线电的思想和组件化方法,研究基于组件的数字解调器软件重构技术设计了解调器软件重构模型来解决重构的难题,并建立了解调器开发组件库。基于研制的组件库及解调器软件重构模型,以16QAM连续信号解调为目标,设计并基于新组件进行集成化开发,形成新的功能。通过测试,从误比特率对比验证重构的正确性及源代码复用率分析的角度证明,新方法的开发效率提高了71.63%。

Abstract:

With the increasingly development of communication system, the corresponding demodulation algorithm also takes on a variety of forms. Combined with the application of the software radio technology, it is more and more important to research the efficient and fast way of modem development. Using the idea of software radio and the method of componentization, the study investigated the demodulator software refactoring technology based on component and designed the model of modem software refactoring to solve the problem of refactoring and form the modem development component library. Based on the developed component library and demodulator software reconstruction model and aiming at the 16QAM continuous signal demodulation, the proposed paper designed and implemented integrated development based on new components to form new functions.

Key words: software radio, componentization, demodulator, software refactoring, component library, reuse rate
