基于最小二乘法（LS）的信道估计

用对分法求非线性方程f(x)=0的实根.基本思想：逐步缩小这个有根的区间，当这个区间长度减小到一定程度是，就取这个区间的中点作为根的近似值-Use of sub-method of nonlinear equation f (x) = 0 the real roots. The basic idea: to gradually narrow the range of this well-established, when the interval length decreases to a certain extent, we take the midpoint of this range as the root approximation

kdtree树的java实现算法,Kd-树 其实是K-dimension tree的缩写，是对数据点在k维空间中划分的一种数据结构。其实，Kd-树是一种平衡二叉树。

这是一个分治法应用的又一个例子,利用分治技术,做大整数乘法,尤其是几百位数以上的乘法,比一般的方法快很多,仅次于快速傅立叶变换.-This is a partition of the application also an example of the use of the partition, bigger integer multiplication, especially above the median of hundreds of multiplication, than the much faster after the Fast Fourier Transform.
