this is for the time varying system response or channel behaviore

说明：  希尔伯特 黄变换中EMD分解函数以及信号的时频特性希尔伯特谱函数的源代码(matlab source code examples of simple applications, simple to use easy to understand for beginners.)

输入经度、纬度和高度，计算任意近地面的重力场(Enter the longitude, latitude and altitude, calculation of arbitrary gravitational field near the ground)

说明：  灰色预测是就灰色系统所做的预测。所谓灰色系统是介于白色系统和黑箱系统之间的过渡系统。(Grey prediction is the prediction of grey system. The so-called grey system is a transitional system between the white system and the black box system.)

这是一个很基本的pso算法的matlab的源码。比较的简单，但是可以再这个基础上修改的(This is a very basic PSO algorithm matlab source code. Comparison of the simple, but can be modified based on this)

matlab GUI 中一些简单控件的创建，有需要的可以看一下！(some examples about matlab GUI uicontrol!)

Free Space Path Loss Model

A 16F84A based timer for applications that need a timer.

加性噪声以及jakes信道模型的代码，对新手可以起作用。(Additive noise and the code of the jakes channel model can play a role for novices.)

这是我的adsp的project 维纳滤波在语音增强上的应用，是基于维纳滤波的语音增强的matlab实现，其中包括matlab源码，word文档，以及PPT。并设计了简单的 GUI 对语音信号进行加噪处理，然后再其进行维纳滤波。通过gui可以实时改变加入噪声的参数和维纳滤波器的参数，进行分析。并 有频谱显示和语谱对比显示。(This is my project adsp the Wiener filter applied on speech enhancement is based on the Wiener filter speech enhancement matlab implementation, including matlab source code, word documents, and PPT. And designed a simple GUI for adding noise speech signal processing, then it Wiener filtering. You can join the real-time changes in the parameters and noise parameters Wiener filter through gui, for analysis. And a spectrum display and spectral contrast display language.)
