PRBS

这是一个由我本人亲自编写的提取图像特定部分的MATLAB程序。通过使用这个函数，你可以轻而易举地将图像的特定位置用白色矩形线框加以圈定、显示。(If you want to circle the specific area of an image, this little program is much more practical and convenient, thus will help you to mark any area of the image with with rectangle.)

用于提高多维时间序列处理效率的自底向上分段法(Used to improve the processing efficiency of multidimensional time series segmentation bottom-up method)

matlab时频分析工具箱时频分析工具箱time-frequency analysis toolbox 第二代，比第一代增加了许多信号处理的函数，有些函数进行了功能的增进。使用的时候，解压到MATLAB安装目录的toolbox目录下，并在matlab中将其添加到搜索路径中使用。(time-frequency analysis toolbox matlab second generation than the first generation adds many signal processing functions, some functions have been enhancing features. Use it, extract it to MATLAB installation directory toolbox directory and search paths to work.)

产生雷达巴克码（Barker）信号，码内线性调频（LPM）。 RD_wave_mix.m 产生Baker码信号函数 test_wave_mix 测试函数(The Barker code (Baker code) radar signal, linear frequency modulation (LPM). RD_wave_mix.m Baker generated code signal function test_wave_mix test function)

利用MATLAB开发软件进行编程，实现了数字IIR低通滤波器的功能，程序直接可以运行！(Use MATLAB to develop software for programming, implementation of digital IIR low-pass filter function, the program can run directly!)

Matlab 模拟声波传数，包括基带调制、数字上变频、数字下变频、滤波、译码等(Matlab to simulate the sound wave number, including baseband modulation, digital frequency conversion, digital frequency conversion, filtering, decoding, etc)

用混沌形成一个序列然后对图像进行排序置乱和异或加密处理，效果很好(Forming a chaotic sequence and then sort of image scrambling and XOR encryption process, with good results)

运用误差矢量幅值法(EVM)对信号的载噪比进行估计(Method using error vector magnitude (EVM) of the carrier signal-to-noise ratio estimate)
