use to simulate how to make spectrum sensing in cognitive radio using energy detection

该文件是包含通信系统ARMA方法的诸多程序，是信号处理的主要部分，希望对大家有帮助。(The document is ARMA methods of communication systems include a number of procedures is a major part of signal processing, and they hope to help everyone.)

说明：  该软件和代码实现的功能是对图象的加密和解密,运行环境是Xp+matlab,代码中有说明,很容易看明白.(the software code and the functions of the image of encryption and decryption, the environment is Xp Matlab, the code is described, it is easy to see to understand.)

这是SAR成像的RD算法仿真，其中包含有最邻近插值(This is the SAR imaging RD algorithm, contains RCMC)

对于阵列天线以及其他种类天线的2维及3维仿真，可以调节波长，天线长度，以及倾角等参数。(For 2-dimensional and 3-dimensional simulation of the array antenna, and other types of antennas, the wavelength can be adjusted, the antenna length, and the inclination and other parameters.)

这个文件夹里是matlab求三对角矩阵的特征值的一个例子。(This folder is a tridiagonal matrix matlab find the eigenvalues of an example.)

说明：  曲线拟合matlab程序 这是我从别的地方得到的跟大家分享(curve fitting matlab program i m glad to share the program with everyone)
