| 摘 要： | 本文介绍了一种基于LabVIEW7.0平台的数字调制信号解调分析软件的设计过程,并给出该软件的设计界面及核心算法的结构框图与具体实现.结合NI PXI-5124数据采集卡及数字正交解调的基本原理,该软件可实现对离散化的数字调制信号进行解调分析,同时直观地显示处理结果.结果表明,该软件在保证低的误码率基础上能满足高性能解调分析仪的要求.同时,利用LabVIEW7.0这种图形化的编程语言在界面设计及控制实现方面的简洁、直观性,该软件的开发周期得到了明显的缩短.

| Abstract: | This paper introduces the detailed design of software for demodulating the digital demodulation signal on the platform of NI LabVIEW7.0 and presents the designed soft panel,the key arithmetic frame for signal processing and its implement.Combined the NI PXI-5124 digitizer with the principle of digital quartered demodulation,the software demodulates the dispersed signal efficiently while showing the results perspicuously.Results show that the software can satisfy a low error code ratio at the same time meeting the requirements of a high-powered demodulating and analyzing device.The development period of this software is reduced evidently making use of labVIEW7.0 designing the interface and control easily. |
