课程作业时的Kmeans分类聚合算法代码

在图像上指定位置做数字标记，这在图像匹配等实验时很有用。(The image digital mark made on the specified location, this experiment in image matching is useful.)

实现信号的DSB,FM，PM,FSK的调制与解调，同时包含加噪声处理。(Implement signal DSB, FM, PM, FSK modulation and demodulation, while including additional noise processing.)

此代码通过随机生成二进制码，对其进行二进制差分调制，以及加入高斯白噪声后对其解调计算误码率，绘制出其输入信噪比与输出信噪比的实验曲线及理论曲线的比较。(This code generates binary codes randomly, modulates them by binary differential modulation, demodulates them with Gauss white noise and calculates the bit error rate, draws the experimental curve and theoretical curve of their input signal-to-noise ratio and output signal-to-noise ratio.)
