基于Qt的通信信号分析软件的设计与实现

Design and implementation of communication signal analysis software based on Qt

针对通信信号分析,传统方法一般采用频谱仪、示波器等通用仪器,不仅价格高昂,而且操作复杂,不具备便携性。自主设计并开发了一款基于Qt图形界面,使用MDI(Multiple Document Interface)框架实现的多窗口实时操作、多功能、多任务并行的通信信号分析软件。软件基于模块化设计,包括离线数据获取、时频图分析、信号参数测量、信号解调等模块。利用线程池数据处理+GUI绘图方式实现对离线信号的全面分析。经过多种信号及环境测试,软件整体具有分析效果佳、兼容性强、便携性高等众多优势,能够达到预期设计要求。

For communication signal analysis,traditional methods generally use general-purpose instruments such as spectrum meters and oscilloscopes,which are not only expensive but also complicated to operate and not portable.A multi-window real-time operation,multi-functional and multi-task parallel communication signal analysis software based on Qt graphical interface and using MDI(Multiple Document Interface)framework is designed and developed.The software is based on modular design,including offline data acquisition,time-frequency diagram analysis,signal parameter measurement,signal demodulation and other modules.It realizes comprehensive analysis of offline signals by using thread pool data processing+GUI drawing.After various signal and environment tests,the software as a whole has many advantages such as good analysis effect,strong compatibility and high portability,and can meet the expected design requirements.
