this source code is useful to do cdma simulation in awgn channel..

说明：  matlab实现的arnold置乱变换,很好用(matlab implementation arnold scrambling transformation, useful)

image compression algorithm

TIN是一种常用的数字高程模型表示方式，这里是Delauney TIN 生成的源码.c(TIN is a regular and efficient represention of digital elevation mode, here is the code for creating delauney triangulate irregular network)

利用LSB算法去实现了电子水印技术。代码完全实现了嵌入以及提取， 算法同时包含了4种攻击算法以及利用psnr测量提取的水印和攻击后提取的水印(This algorithm describes digital watermark technique by using LSB. This code implement embedding and extraction. At the meanwhile, this algorithm includes 4 different kinds of attacks and in the end, measure psnr between extracted watermark and attacked extracted watermark)

认知无线电功率控制方面一些重要参考文献，对研究功率控制方面的初学者很有帮助(Cognitive radio power control some important references，the study of power control for beginners is helpful)

次程序为PID程序,可以认真学习后得出想要的结果(It s PID program.)

V BLAST using zero forcing and symbol cancellation.

使用有限时域差分法，用matlab模拟三维光子晶体(the simulation of TM mode in three-dimensional photonic crystals)

离群点检测的算法，适应于MATLAB，包含关于距离和LOF的聚类算法(Outlier detection algorithm, adapted to MATLAB, including distance and LOF clustering algorithm)
