用Matlab实现随机信号的实时处理

Realize the real-time processing of random signals by Matlab

在实时控制系统设计中经常需要对各种随机信号处理的算法进行调试,但组建完成一个健壮的硬件系统也要经过反复的测试,会花费较长的时间和较高的硬件成本。文中提出一种基于Matlab DAQ工具进行随机信号实时处理的方法,该工具借助Matlab对硬件良好的支持以及丰富的处理函数,在上位机上直接组建一套稳定的信号处理系统,以实际环境中音频混响信号的处理为例,实现了随机信号的实时采集、计算以及数据结果可视化的集成处理,处理过程显示了Matlab对实时信号处理的便捷性、高效性。

In the design of real-time system,the processing algorithms of random signals should be tested,but to build a robust hardware system should also be tested again and again,this takes so long time and adds so expensive hardware cost.A method based on Matlab DAQ is proposed,and with the help of Matlab’s good hardware compatibility and rich processing functions a stable signal processing system on the computer is set up.Taking audio reverberation signal processing in real environment as an example,the way realizes a integrated processing on signal acquisition,calculating and data visualization,and the example shows the convenience and efficiency of Matlab in real-time signal processing.
