ofdm有关信噪比与误码率的matlab仿真，包含QPSK星座图。(Matlab OFDM simulation of the signal to noise ratio and the bit error rate, contains the QPSK constellation.)

实现hsi颜色空间到rgb颜色空间的转换，还有rgb到hsi的转换，(Achieve hsi color space to the rgb color space conversion)

Lorenz 吸引子三维相空间图，这里用四阶 Runge-Kutta 法得到微方程的离散序列(Lorenz Runge-Kutta)

pcm编码，译码。实现单频正弦波输入信号的模拟。(pcm coding，decode)

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)
