QPSK

对一篇文章中的文字进行比例分析并能求出出现频率最多的字。(Of an article in the proportion of text analysis and to derive a maximum frequency of occurrence of the word.)

求频率响应的程序，里面提供了三个求的方法，经过本人调试(frequency response)

this is a matlab program

本程序实现对图像的打开、退出操作，以及图像旋转、添加噪声、图像平滑（椒盐噪声处理、均值低通滤波处理、中值滤波处理）、图像直方图显示、预测编码，在MATLAB中用GUI实现。(This program implements the image is opened, quit the operation, as well as image rotation, adding noise, image smoothing (salt and pepper noise processing, the mean low-pass filtering, median filtering process), histogram display, predictive coding, in MATLAB using GUI implementation.)

现今阵列应用中，宽带信号的处理越来越多。由同心圆阵组成的多圈圆形阵列在宽带信号处理上有更强的优势。和单圈均匀圆阵相比，同心多圈圆阵的嵌套设计阵列工作频率范围更宽，同时，灵活性增强。 (Nowadays array applications, the broadband signals in many more and more treatment. By the array composed of many concentric circular ring array of broadband signal processing at up there is more advantage. And single-lap compared to uniform circular array, circular array concentric circle many nested design frequency range of a broader array of work at the same time, enhance flexibility.)

MATLAB遗传算法的经典程序,有例子,值得研究一下,应该有帮助.(MATLAB GA classic procedures, is an example worthy of study, should help.)

最小二乘算法来实现esprit算法，该代码已经在matlab中运行过绝对可以放心使用(Least squares algorithm to achieve esprit algorithm, the code has been run in matlab absolutely safe to use)
