8QAM
利用Matlab仿真软件，完成如图1所示的一个基本的数字通信系统。信号源产生0、1等概分布的随机信号，映射到16QAM的星座图上，同时一路信号已经被分成了实部和虚部，后边的处理建立在这两路信号的基础上。实部、虚部信号分别经过平方根升余弦滤波器，再加入高斯白噪声，然后通过匹配滤波器（平方根升余弦滤波器）。最后经过采样，判决，得到0、1信号，同原信号进行比较，给出16QAM数字系统的误码。(Using Matlab simulation software, as shown in Figure 1 to complete a basic digital communications systems. Signal source such as arise over the distribution of 0,1 random signal, is mapped to 16QAM constellation diagram, at the same time all the way the signal has been divided into real and imaginary parts, behind the deal with the establishment of these two signals in the basis. Real part, imaginary part of the signal, respectively, after a square root raised cosine filter, then add white Gaussian noise, and then through the matched filter (square root raised cosine filter). Finally, after sampling, the verdict has been 0,1 signal, to compare with the original signal is given 16QAM digital system error.)

PCM
本程序可以对一个模拟信号进行数字化，使用的是PCM即脉冲编码调制，其结果是将样值转化为8位PCM编码。现今语音编码大多数采用这类编码方法(This procedure can be an analog signal to digital, using pulse code modulation or PCM, and the result is kind of value will be translated into eight PCM coding. Most of the current speech coding to adopt this type of coding method)

camener
此程序主要是检测黄色区域（用于人脸识别）
所用摄像头为USB320X240RGB的
原理：
先利用颜色找出符合条件的大面积黄
再利用模板闭运算补充连通与
再利用XY轴上连同域的寻找
标出人脸(The procedure is to detect the yellow area (for recognition) camera for USB320X240RGB used the principle: first, to identify qualified by the color yellow and then use a large area of the template to add connectivity and re-closing operation axis together with the domain using the search XY Face marked)
