摘要
利用LabVIEW灵活的图形编程及Matlab的数学计算能力进行了虚拟小波消噪仪设计.虚拟消噪仪仪器面板采用系统选项卡方式设计,并通过调用LabVIEW环境中的Matlab Script节点方式实现与Matlab程序进行通信接口.在虚拟小波消噪仪软件中实现了小波阈值法、小波包法和模极大值法去噪,可对小波函数、分解层数、阈值选择、阈值类型等进行选择;去噪处理结果自动保存为Excel文件.仿真去噪结果验证了虚拟小波消噪仪功能及去噪算法的有效性.
The virtual wavelet denoising instrument was designed by using LabVIEW flexible graphics programming and Matlab calculation ability,and the panel of virtual denoising instrument was designed by the way of system TAB.In LabVIEW environment,achieve communication interface LabVIEW and Matlab through the Matlab Script node.In the software of the virtual wavelet denoising instrument,signal denoising of wavelet threshold value method,wavelet packet method and modulus maximum value method,and select wavelet function,decomposition layer,threshold and threshold type was realized.The de-noised results were automatically saved as excel files.At last,it is proved that the virtual wavelet denoising instrument function and the denoising algorithm are effective by simulation results.
