双极性归零码的功率谱密度(Bipolar power spectral density of NRZ)

信号编码使用hdb3码，其解码程序，可以防止连0和连1对信号造成的干扰(hdb3 code decoding process)

说明：  MATLAB在电子信息工程中的应用[张德丰][程序源代码](MATLAB in Electronic Information Engineering [Zhang Defeng] [source code])

说明：  matlab的简单练习，对图像进行基本操作。课堂练习而已(matlab simple exercises, perform basic operations on the image. Workshop only)

完成对于图像的DCT变换反变换，FFT变换反变换，动态模糊，加噪声去噪声等等，配有图形界面，功能强大(For complete image DCT transform inverse transform, FFT transform inverse transform, as well as some dynamic blurring function, and with a graphical interface)

灰色关联算法的MATLAB仿真实现，可用于态势预测(MATLAB simulation gray correlation algorithm, can be used to predict the trend)

matalab程序好用便捷，关于宏观经济，有增长，有波动研究。(matalab program easy to use and convenient, on the macro economy, there is growth, there are fluctuations in research.)

kmeans is image segmentation algorithm.

说明：  基于背景差分法和帧间差分法的目标跟踪 应用了二维滤波，效果较好-(Application of a two-dimensional filtering, target tracking based on background subtraction and interframe difference method better)

Including orbital maneuvering simulation, initial orbit calculation, Machine learning routines, Complete class-based image processing, contains all of the source code, auto image.
