给定一个音频范围内的模拟强噪声随机信号（强噪声+周期信号），将信号从强噪声中提取出来，并计算原信号及提取信号的均值、平均功率、方差、频谱及功率谱密度、互相关等 并附带图形(Given within the scope of an audio simulation of strong noise random signal (noise+ periodic signal), the signal from strong noise in the extracted and calculated signals and extract the original signal of the average, average, variance, spectrum and power spectral density , such as inter-related and incidental graphics)

采用了一种简化的方向图模型。方位和俯仰均用高斯型。(Direction using a simplified graph model. Azimuth and elevation are used Gaussian.)

基于MATLAB的锅炉液位控制系统，采用模糊控制(MATLAB-based boiler level control system using fuzzy control)

matlab实现的目标跟踪数据关联程序，可以用于目标跟踪领域。(matlab implementation of target tracking data association procedure can be used for target tracking.)

从信号处理的角度讲，小波(变换)是强有力的时频分析(处理)工具，是在克服傅立叶变换缺点的基础上发展而来的，所以从信号处理的角度认识小波，需要傅立叶变换、傅立叶级数、滤波器等的基础知识。 (From signal processing perspective, the wavelet (transform) is a powerful time-frequency analysis (processing) tool is to overcome the shortcomings on the basis of Fourier transform evolved, so from the perspective of understanding of wavelet signal processing need to Fourier transform, Fourier series, filters and other basic knowledge.)

说明：  基于EM算法，可以估计在混合高斯分布下的三个参数(EM expection)
