多径多普勒信道模型，包括快衰落，慢衰落，频率选择性衰落，平坦衰落等(Doppler multipath channel model, including fast fading, slow fading, frequency selective fading, flat fading, etc.)

该程序是使用Matlab仿真协同通信的DF（解码转发）基本性能，基本模型S-R-D三个节点，接收端使用MRC（最大比合并）。固定DF由于SR信道的错误，其性能受到限制，在大SNR情况下不能获得有效分集。而当SR距离足够近的时候，可能获得一定的分集增益。(The program is a cooperative communication using Matlab simulation DF (decode forwarding) basic performance, the basic model of the SRD three nodes, the receiver uses the MRC (maximum ratio combining). Fixed DF error of the SR channel, its performance is limited, can not obtain a valid diversity in the large SNR case. When the SR close enough, you may get some diversity gain.)

This a a sphere decoding function. It has low complexity.

the folder gives information about the image forgery detection. detection is made by examining the sift and ransac features of the image. color processing is done as a preprocessing step.

使用WOLA滤波器组的均衡器什么的，网上原来下载的代码不全，补充了缺省的几个函数（也从网上搜来），基本可以运行了(Calibrated parametric equalizer reference implementation using WOLA filterbank,code by Benny S鋖lberg 2010)

贝塞尔曲线拟合程序，完全利用matlab实现(Bezier curve fitting procedures)

Display the analytic solution of the 2D Helmholtz equation for a dielectric cylinder (i.e. the scattered field and the transmitted field). You can specify the following parameters: radius, wave number outside and wave number inside the cylinder.
