一维功率谱密度计算程序，可以选择是否加窗，加那种窗(1D power spectral density caculation routin base on fft )

Alamouti的matlab代码，适合初学者(Alamouti)

watermarking using ycbcr and dct

通过仿真,分析了多径效应和多普勒效应的原理.并给出了移动信道的建模方案和程序.每个结论都给出了仿真程序可直接运行.(through simulation, Analysis of the multi-path effects and the principle of Doppler effect. and gives the mobile channel modeling programs and procedures. Conclusion gave each a simulation program can run.)

DS-CDMA仿真-matlab代码，及其代码详细说明(DS-CDMA simulation-matlab code, and code details)

本源代码首先实现普通的直方图均衡化，再实现灰度级之间的均匀分布，可以有效的解决直方图均衡化过程中的灰度断层现象。使得图像更加的柔和，直方图分布更均匀。(Source code first to achieve common histogram equalization, and then to achieve uniform distribution between gray levels can be an effective solution in the process of histogram equalization, gray fault phenomenon. Makes the image more of the soft histogram more evenly distributed.)
