对于通行工程里的两种调制方式PAM和QAM进行了性能仿真，并对他们的性能进行了比较。有信噪比，误码率等重要参数比较。还有具体的文档说明。(For the passage of two works in the PAM and QAM modulation for the performance simulation, and their performance compared. There is signal to noise ratio, bit error rate and other important parameters. There are specific documentation.)

曲面拟合的程序，网上很多地方有，但是都是错的，我改正后上传了(Surface fitting procedure, there are many places online, but it is wrong, I uploaded the corrected)

系统辨识方面的matlab程序，很快迭代算出结果(System identification in the matlab program, quickly calculate the results of iterative)

自己编写的matlab程序，采用Prewitt和Sobel算子，初学者相互学习。(I have written matlab program using Prewitt operator and Soble operator handling. Beginners learn each other.)

用matlab中simulink工具箱搭建的非线性模型，功能便于实现！(Using matlab simulink toolbox to build the nonlinear model, features easy to implement!)

源代码 用程序得到本机的MAC 地址 工程要经常用到(The source code with the procedures are the MAC address of the machine)

cashcode开发,用于开发接口工具，测试等(cashcode Developmentcode)

视频检索，图像识别等方面的内容，用于matlab(Video retrieval, image recognition and other aspects)

Measure the performance of three modulation techniques using PAPR, spectral efficiency, BER

基于BLACKMAN窗的自相关周期图法功率谱估计，希望对大家有所帮助。(BLACKMAN-based window autocorrelation Periodogram power spectrum estimation, we want to help.)
