Gauss channel generation with zero mean and unit variance

利用陈超混沌映射，可以产生超混沌序列，这种序列具有类随机性、难以预测性广泛的应用与图像、视频加密领域(Chen Chao use chaotic maps can produce super-chaotic sequence, this sequence has randomness, unpredictability of the wide range of applications and images, video encryption field)

利用DFT分析离散信号频谱的实验。利用FFT分析信号 x[k]=cos(3pik/8 +pi/4 ) 的频谱；确定DFT计算的参数，绘出其频谱；并进行理论值与计算值比较。(DFT analysis of discrete signal spectrum utilization experiments. Analysis using FFT signal x [k] = cos (3pik/8+ pi/4) of the spectrum determine the parameters of DFT calculations, draw its spectrum and comparing the theoretical and calculated values.)

说明：  本程序实现的功能是：bpsk在matlab上的调制解调(modulation and demodulation of bpsk on matlab.)

说明：  遗传算法求解优化问题的一个程序，学习matlab时可以参考一下(Genetic Algorithm Optimization of a process)

字母图像识别算法，O, E, A, U 四个字母进行识别，该算法加入一定噪声之后依然有效。(The basic goal of the program is to perform letter recognition of vowels O, E, A, U in paragraphs provided in form of black-and-white images. Using the training paragraph image, we are allowed to train our program to distinguish among letters. Some difficulties that need to be resolved are noise, joined letters, scaled or tilted letters, and distinguishing between letters that are similar to each other. )
