这个程序主要是用来设计实现一个加解密的系统 采用matlab设计 用了二进制循环 异或的知识(This program is mainly used to design and implement a system of encryption and decryption using matlab design cycle using the binary XOR of knowledge)

this file is about solair system

稀疏表示，字典学习，初学者，KSVD等等(Sparse representation dictionary learning, beginners, KSVD etc.)

LMS算法去除加噪声音乐程序，效果比较好，有图为证。(LMS algorithm to remove noise adding music program, the effect is better, has a license to the graph. )

说明：  说明： 该课题为基于bp神经网络的中文汉字识别系统，可以用手写板写，现场识别。有界面GUI操作。另外可识别汉字，字母，数字等均可。(Explain: This project is a Chinese character recognition system based on BP neural network, which can be written on handwritten board and recognized on the spot. There is interface GUI operation. In addition, it can recognize Chinese characters, letters, numbers, etc.)

to generate the white noise signal u(n) with uniform distribution and power p

qpsk调制在瑞利信道中的性能仿真，以及各个阶段信号的星座图仿真(qpsk modulation performance in Rayleigh channel simulation, as well as the various stages of signal constellation simulation)

说明：  此程序是对数据进行平滑的预处理方法，用来去除噪音的干扰(This program is smoothing the data in order to remove noise interference)

产生BPSK分析信号,可以设置基本S/N比等参数,并对信号画图显示.(Analysis generated BPSK signal, you can set the basic S/N than the other parameters, and signal drawing show.)

用于matlab中图像后处理，将图像灰度化，二值化(For processing the image in MATLAB, the gray image, the value of the two)
