摘　　要：针对目前自适应滤波实验平台价格昂贵、人机交互界面单一等问题,为满足数字信号处理类课程工程性、创新性实验教学的需求,基于NI嵌入式控制器cRIO,设计开发了LMS自适应滤波教学实验平台.该平台通过C系列I/O模块完成真实物理信号的生成与采集,且cRIO控制器完成滤波并与PC交互;PC端HMI通过前面板控件与网络共享变量完成滤波实验系统的参数设置、时频域内滤波过程可视化呈现.Aiming at the problems of high price and single man-machine interface of the adaptive filtering experiment platform,an LMS adaptive filtering teaching experimental platform based on NI CompactRIO(cRIO)was designed and developed to meet the needs of engineering and innovative experimental teaching of digital signal processing courses and to enhance students'practical and innovative abilities.In the platform,C series I/O modules and cRIO collaboratively complete the generation,acquisition and filtering of real physical signals.The PC-side HMI(Human Machine Interface)uses front panel controls and shared variables to complete the setting of signal parameters and filtering parameters,and to complete the visual presentation of the filtering process in the time-frequency domain.
