QPSK在加性高斯白噪声环境下，信噪比和误码率的仿真。 先产生一个四组符号的序列，再将该序列映射到对应的相位上。用相应的函数产生均值为零、方差为δ2的加性高斯噪声。 (QPSK the additive white Gaussian noise environment, and the signal-to-noise ratio of the simulation. First group have a four symbols of sequence, then this sequence mapped to the corresponding phase on. With the corresponding function have zero mean and variance of 未2 additive white Gaussian noise.)

I need the matlab codings for medical image proccessing for eg:downsampling,bicubic interpolation

利用matlab写的较基本的arnold加密与相应解密算法，其中的key可以任意改之，但加密次数不宜太多，最好在100次以内(Use matlab to write the basic Arnold encryption and decryption algorithm, one of the key can be arbitrary change, but the number of encryption shoulds not be too much, best within 100 times)

这个是用阶跃风速、风轮、传动系统以及转速控制器的模型，来观测风力发电机的阶跃相应(This step is to use the wind speed, wind turbines, transmission system and the model of the speed controller to measure wind generators step accordingly)

说明：  利用matlab的gui设计的带有输入和输出功能的界面图形，可视性很强，自己独立编写的数据和图形，学习非常值得(Uses the Matlab GUI design to have the input and output function the interface graph, the visibility is very strong, the data and the graph which oneself compiles independently, the study is very worthwhile.)

一个开环滤波器的设计程序，是用MATLAB实现的，值得初学者下载(An open-loop filter design procedures, using MATLAB, it is worth downloading for beginners)

说明：  电力系统中matlab潮流计算所需要的节点注入功率母线数据等等30、69节点(Node injection power bus data for power flow calculation of MATLAB in power system and so on)

VBLAST源代码！ 下载后将.rar去掉，即可！ 文件也可用ultraedit等软件直接打开(VBLAST source code! After downloading. Rar removed can be! Documents available ultraedit software directly open)

基于K-L变换下的人脸检测程序，用matlab编写的(KL transform based face detection under the program, using matlab)

实现模糊聚类,包含一个主函数mohu和两个子函数Form_B和search_B( achieving vague cluster,including one main function and two sub function named Form_B and search_B)
