这是学习MIMO卫星通信系统，信道容量与信噪比之间关系的一个好的案例(MIMO matlab SNR)

自适应粒子群优化更新算法，在MATLAB环境下仿真运行，程序代码能够正确运行。(A viable particle swarm optimization to update algorithm, MATLAB code to run correctly simulation, ease of use.)

Root Mean Square Error

Yen threshold method realized in Matlab environment based on Yen J.C., Chang F.J., and Chang S. (1995) "A New Criterion for Automatic Multilevel Thresholding" IEEE Trans. on Image Processing, 4(3): 370-378

In this project, we have designed and implemented a method to estimate the dual frequencies in sinusoids immersed in additive white Gaussian noise. The Cramér-Rao lower bound (CRLB) for the signal model and a nonlinear least square frequency estimator are derived. The estimator is evaluated by numerical examples.

actionscript 3 tutorials. this might help. i hope

This is an MMC model for matlab

选择两张图片，一张水印图，一张嵌入图，将水印图进行Arnold置乱算法将其置乱，嵌入到嵌入图中，形成数字零水印，选用白噪声、高斯低通滤波、压缩、剪切、旋转攻击测试。以此观察图像鲁棒性(Select two pictures, a watermark and an embedded graph. We will scramble the watermark image with Arnold scrambling algorithm and embed it into the embedded map to form digital zero watermark. We choose white noise, Gauss low pass filtering, compression, shearing and rotation attack test. To observe the robustness of the image)

说明：  信号特征提取matlab实现代码，包括时域、频域、时频域分析。具体使用根据自身需要改进。(Signal feature extraction matlab code, including time domain, frequency domain, time-frequency domain analysis. Specific use according to their own needs to improve.)
