matlab的基础教学，对于从来没有学习过matlab的同学，该文档可以提供由浅入深的详细介绍与说明。(matlab basis for teaching, never studied matlab for students, the document provides a detailed description and explanation progressive approach.)

基于四阶累积量特征分解的空间谱估计测向方法（信号处理的论文算法仿真 未找到分类）(Based on the fourth-order cumulant eigen-decomposition to the spatial spectrum estimation method (the paper algorithm simulation of the signal processing is not found Category))

用median 滤波除去图像中的pepper and salt 噪声，并且给给出了lena图像和coin图像的示例(use median filtering to remove the noise of pepper and salt， give examples of lena andcoin)

无线通信中采用Dent模型的瑞利衰落信道产生器(Dent model used in wireless communications, Rayleigh fading channel generator)

平稳随机信号谱估计 使用两种谱估计方法将信号和噪声分离：周期图法谱估计和Levinson-Durbin递推法谱估计。其中每种方法又细分为自编程序和使用matlab自带函数两种。( Random signal model is estimated using two methods of spectrum signal and noise separation: periodogram spectral estimation method and Levinson-Durbin recursive spectrum estimation method. Each method which is divided into self-fine procedures and the use of two matlab own function.)
