中文说明：虚拟力的无线传感网络覆盖，有小波分析的盲信号处理，对于初学者具有参考意义，表示出两帧图像间各个像素点的相对情况，对信号进行频谱分析及滤波，使用混沌与分形分析的例程，针对EMD方法的不足,随机调制信号下的模拟ppm。
English Description：
Virtual force wireless sensor network coverage, wavelet analysis of blind signal processing, for beginners with reference significance, showing the relative situation of each pixel between two images, signal spectrum analysis and filtering, using chaos and fractal analysis routines, aiming at the shortcomings of EMD method, random modulation signal simulation.
