Propogarions methos for Wimax

实现最小交叉熵 最大熵 OTSU算法的小程序 简单实用(Minimum cross entropy maximum entropy OTSU algorithm procedure is simple and practical)

DES function for the encryption of DES,use matlab to make it possible,first input in the function is plaintext ,second one is key,and last is to choose encrypt or decrypt

最小均分误差均衡的matlab程序。学习LMS算法必备。(Minimum Mean Square Error equalizer matlab program. Learning LMS algorithm necessary.)

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.)

从曲线中检测到其峰值：先利用二次求导得到所有凸点，设置门限，去除过低的凸点，然后利用滑动窗的方法，在凸点中求得满足峰值要求的点(Detected from the curve to its peak: the first use of the second derivative method to get all the bumps, set the threshold too low to remove the bumps, and then use a sliding window, obtained in a bump to meet peak requirements of point)

It simulates the transient and ac analysis of simple rc circuit.

本matlab程序实现地球和天球坐标间的转换，对于天文和航天领域的初学者有一定帮助(Terrestrial and Celestial Coordinate transform)
