摘　　要：借鉴偏微分方程在图像处理中的良好表现,将其引入到一维信号的处理中来.该文首先对扩散方程下的信号去噪模型进行了阐述,然后将其离散化并使用G语言进行了软件实现,最后在Labview环境下进行仿真.结果表明,扩散方程能有效抑制信号中的噪声,适用于信号的提取.Using the good performance of PDE in image processing for reference,it is introduced into one-dimensional signal process ing.In this paper,the signal de-noising model under the diffusion equation is first described,then it is discretized and realized by G lan guage software,and finally it is simulated in LabView environment.The results show that the diffusion equation can effectively suppress the noise in the signal and is suitable for signal extraction.
