基于LabVIEW的数字基带信号码变换系统仿真设计

Design of digital baseband signal number conversion system based on LabVIEW

以LabVIEW软件为平台设计数字基带信号码变换器系统,利用LabVIEW软件的可视化优势,设计的系统具有用户登录、系统状态显示、码型变换和波形显示模块功能的控制界面,可实现AMI码、HDB3码、PST码、双相码、Miller码、CMI码6种输出码型的变换,实践证明,该码型变换系统操作方便、界面友好、稳定可靠,可快捷准确的实现常见传输码型的变换,同时在通信原理课程教学中有很大的应用价值。

Based on LabVIEW software platform design of digital baseband signal code converter system, using the visual advantage of the LabVIEW software, system design with user login, system state display, code conversion and waveform display control interface function module can implement AMI code and HDB3, PST code, double phase code, Miller code and CMI code 6 code output type transform. The results show that this type of code transformation system has the advantages of convenient operation, friendly interface, stable and reliable, common code transform to realize fast and accurate, at the same time, it has great application value in the teaching of communication principle.
