软件无线电资料我的大作业，喜欢的人可以下下来自己看看吧(Software Radio information my large work, like people can look at themselves down under the bar)

说明：  图像的置乱加密和解密算法，需要输入加密密钥进行加密，然后只能输入相同的解密密钥才能得到原图像(Image scrambling encryption and decryption algorithms, need to enter the encryption key to encrypt, then enter the same decryption key only to get the original image)

SM系统matlab程序，传输天线、接收天线数量可调，信号调制方式可调，循环次数可调。最后生成BER性能曲线，并将不同SNR下的BER数据存储到mat文件中。(SM system matlab program, the number of transmission antennas, a receiving antenna is adjustable, adjustable signal modulation scheme, the number of cycles is adjustable. Last generate BER performance curve, and store data in different SNR BER under the mat file.)

边界延拓镜像法和边界延拓自适应波形匹配法(Boundary extension by mirror and adaptive wave matching)

说明：  对前面fish1的进一步修正，完善调光功能的稳定性，和可靠性(another menage the brightness)

一个完整的SVM分类器的程序，matlab编写的。(A complete program SVM classifier.)

images and logfile messages

说明：  MATLAB编程（英文影印版第二版），老师给我们推荐的一本书，觉得不错，发给大家。(MATLAB programming (Degowin 2nd edition), we recommend to the teachers of a book, think it's good, to everyone.)

地震波阻抗反演，用于一维、二维褶积模型，其中梯度函数和目标函数根据自己的需要建立(Seismic impedance inversion, for one-dimensional, two-dimensional convolution model, in which the objective function and the gradient function according to their own needs to establish)

基于人工神经网络的常用数字信号调制，isodata 迭代自组织的数据分析，现代信号处理中谱估计在matlab中的使用。( The commonly used digital signal modulation based on artificial neural network, Isodata iterative self-organizing data analysis, Modern signal processing used in the spectral estimation in matlab.)
