16QAM预失真 通过信道 及附加白噪声(16QAM pre-distortion by the channel)

说明：  想学LTE系统相关知识的朋友可以看看这本经典书籍(Want to learn the system knowledge LTE friends can look at this classic book)

Writes a mesh to a ply file (text format) wich can be read by PlyView from Cyberware and Scanalyze from Stanford University. Both are available for free

说明：  利用MATLAB实现一个BP网络的控制程序。简单使用(Use MATLAB to achieve a BP network control procedures. Simple to use)

This is the source code for 2D metrics in gird generation.

经改进的希尔伯特——黄分解，效果不错，在MATLAB中实现(Improved Hilbert- Huang Decomposition, good results in MATLAB to achieve)

这是matlab图像处理的资料，里面主要是图像处理的常用函数介绍，很全面(This is the Matlab image processing information, which is commonly used in image processing functions, the very comprehensive)

用MATLAB程序演示灰度调整，对比度增强，直方图均衡，局部平滑，中值滤波，频率域平滑与锐化，用MATLAB编写有关程序(failed to translate)

该程序主要用于matlab对图像进行区域检测分割 其原理是区域生长法 需要自己设定阈值 选取生长点(The program is mainly used matlab image area detection principle is divided region growing needs its own set threshold growing point)

matlab 数字图像信号的频域分析及仿真 将二维数字图像进行傅立叶频域分析，并且做了图像幅度谱重建和相位谱重建，通过这个例子大家可以明白相位比振幅更重要。(matlab digital image signals in frequency domain analysis and simulation of two-dimensional digital image Fourier frequency domain analysis, and has done a reconstruction of the image amplitude spectrum and phase spectrum reconstruction, by this example we can understand the phase is more important than the amplitude.)
