基于最小二乘法（LS）的信道估计

将正整数分解为素数之积- Decomposes the positive integer product of into the prime number

这是遗传算法在 C# 中的一个简单实现。该应用程序将对基因组进行分类。

c语言源代码，可以计算两条直线交点的坐标。-c language source code can be calculated two straight intersection coordinates.

最小二乘法一般是用来拟合直线和一些线性数据的，就是用一条直线来尽可能的表达若干的点的趋势，当然直线穿过所有的点是最好的，但往往有误差存在，所以拟合出的直线要求误差最小.设这些点为(x1,y1),(x2,y2)....(xn,yn).拟合直线为y=kx+b.-Ordinary least squares method is used to fit a straight line and a number of linear data, that is, as far as possible with a straight line to the point of the expression of a number of trends, of course, a straight line through all the points is the best, but often there is a margin of error, Therefore, a straight line fitting the requirements of the smallest error. established for these points (x1, y1), (x2, y2 )....( xn, yn). fitting straight line y = kx+ b.

GN算法的JAVA实现, 需要安装Graphviz2.38等能够直接生成图像, 如不需要, 请自行修改相应代码.

约瑟夫问题的一种描述是：编号为1，2，…，n的n个人按顺时针方向围坐一圈，没人持有一个密码。一开始人选一个正整数作为报数上限值m，从第一个人开始按顺时针自1开始报数，报到m是停止报数。报m的人出列，将他的密码作为新的m值，从他在顺时针方向上的下一个人开始重新从1报数，如此下去，直至所有人全部出列为止。-a description of the problem is : No. 1, 2, ..., n n clockwise direction by individuals sitting around a circle, no one holding a password. One person started as a positive integer limits on the number of reported m, from the first individuals to embark on the clockwise from a few reportedly started, the report m is reportedly stopped a few. M reported out of the list of his password as a new value m, from a clockwise direction in the next re-started from a newspaper a few, like that, until the total of all listed so far.

检查图片中属于人类肤色的区域。输入为yuv格式图片，目前可以识别黄种人的肤色区域。主要用到椭圆模型的色彩识别算法，在yuv色彩空间中，将近似黄种人肤色的色彩，用uv二维空间中的椭圆区域来表示。

应用背景On the Design of ZF and MMSE Tomlinson-Harashima Precoding in Multiuser MIMO Amplify-and-Forward Relay System,it is main described the mimo system in the multi-user  scenario.the main precoding algrithm is combined the zf precoding and the MMSE precoding.关键技术we design a zero-forcing (ZF) Tomlinson-Harashima precoding (THP) and a minimum mean square error (MMSE) THP for multiuser MIMO relay system with direct link. Based on these precoding structures, we propose the optimal combining weights of the ZF THP and the MMSE THP in half duplex relay system, and the sub-optimal weights of MMSE THP to reduce feedback channel state information(CSI). Through the Monte Carlo simulation, we verify that the optimal weights combining method outperforms the constant weights combining method. In addition, we confirm that the performance of the sub-optimal weights combining method is&

此源码实现的功能: 是对Camera采集的图像进行校正处理。 具体是：通过输入一组的黑白相间的棋盘格的图像，检测黑百格图像的焦点位置来矫正使用 透镜给针孔模型带来的孔型的误差，我们可以使用从不同角度去采集图像，根据不同位置的图像的 角点信息，来近似估计其矫正矩形参数，从而得到较好的图像。其原来是基于张学友的标定算法， 利用OpenCV来实现的，是经过测试的。
