摘要
针对市场上缺少专用无线电通信信号发生器的现状问题以及项目需求,利用虚拟仪器技术,结合移动通信信号的特点,以计算机中Visual C++6.0平台为基础,设计了一种应用于分析移动通信信号的信号发生器软件。首先,实现了常用信号源的产生,如正弦波、三角波、方波等;其次,重点实现了WCDMA下行广播信号的产生;然后,利用MFC中CDC类成员函数对产生的信号进行了图形绘制与显示。通过与实际采集的实时数据对比分析表明,设计的信号发生器所产生的WCDMA下行广播信号符合需求。
To solve the problem on lack of special wireless telecommunication signal generator on the current situation of China market and meet the requirements of the project,we designed a signal generator software applied to analysis of the signal in mobile communication. This software is based on Visual C＋＋6. 0 platform, mainly applied virtual instrument technology,and combine with the feature of the wireless signal. Firstly, it successfully produced common signal sources include sine wave, triangular wave, square wave, etc. Secondly, focus on producing WCDMA Downlink broadcast signals. Finally, draw the graphics of these produced signals and display them successfully via the CDC member functions of MFC. After compared with the real-time data from actual collection, the analysis result shows that the WCDMA Downlink broadcast signals produced by the signal generator designed in this paper could meet the requirements.
