matlab code for space time coding

上传一个解方程的matlab主程序mw文件，变的不好请谅解(To solve differential equations )

A Special Topic in DSP using Ideal filtering

基于能量检测的频谱感知.由于实际信道中的多径和阴影效应，单个认知用户频谱感知的性能受到影响，因此需要靠不同用户间的协同频谱感知来对抗多径和阴影效应。本设计要求在文中采用一种协作机制，即两用户进行协作频谱感知，提高主用户的检测率，减少检测时间，并且得到捷变增益。要求给出仿真结果。(spectrum sensing in cognitive radio based on energy detection.As the channels in diameter and shadow, not a single user spectrum of capabilities and therefore need different between a user to the spectrum is perceived as more and the effect. this design for the use of a coordination mechanism, the two users collaborate spectrum, the detection rate of increase and decrease the test of time and get a change requires immediate gain. some emulation. )

该功能用matlab实现的几个界面，可供新手们参考学习下哈(This feature is implemented with a few matlab interface for novices to learn under reference Ha)

用于图像处理的独立分量分析，使用大量的有限元法求解偏微分方程，music高阶谱分析算法。( Independent component analysis for image processing, Using a large number of finite element method to solve partial differential equations, music higher order spectral analysis algorithm.)

书本《Matlab数字信号处理与应用》上的matlab程序代码。很全面哦。(Book " Matlab Digital Signal Processing and Applications" on the matlab code. Oh, very comprehensive.)

感应电动机参数辨识算法仿真程序，所有程序都是用M函数编写(simulation program of Induction motor parameter identification algorithm, all programs are written with M function.)

说明：  双馈风机MATLAB仿真，可以直接进行模型搭配和修改，是经典模型(The double fed fan can be directly matched and modified by MATLAB simulation, which is a classic model)
