该matlab程序实现字母T和L的区分，在9*9格形框里，字母T和L有不同的位置，任意位置，神经网络都可以识别出是T还是L(The program matlab and distinguish letters L, T, in the grid-shaped box 9* 9, the letters L and T have different locations anywhere in the neural network can identify a T or L)

matlab程序，采用滤波器进行信号去噪，FFT变换(matlab program using filter signal denoising, FFT transform)

Edge detection result should be enhanced using linear method like Median filter to remove the garbage around the pupil to gain clear pupil to determine perfect centre. Get the centre of the pupil by counting the number of black pixels (zero value) of each column and row. Then get each row and column that has the maximum number of these black pixels. Then determine the center by simple calculation according to the image coordinate to set it correct on the image, consequently we can determine the radius of the pupil. Thus we can find the pupillary boundary (inner). A similar procedure is extended by using a coarse scale to locate the outer boundary (limbus) which can be apparent by using the mid-point algorithms of circle and ellipse.

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.)

有关MPSK调制，传输模型。成型脉冲分为矩形，升余弦脉冲，平方根升余弦脉冲。M的值为2，4和8.所加噪声是高斯白噪声。(Of the MPSK modulation, transmission model. Pulse shape is divided into rectangular, raised cosine pulse, the square root raised cosine pulse. The value of M for 2,4 and 8. The increase in noise is Gaussian white noise.)
