说明：  升余弦信号通过理想信道的误码率计算和绘制误码率曲线(or cosine signal through the ideal channel bit error rate calculation and mapping BER curves)

卡尔曼滤波的理解，利用一个简单的正弦信号来进行卡尔曼滤波，从而更好的理解卡尔曼滤波。(Understanding of the Kalman filter, with a simple sinusoidal signal to the Kalman filter so as to better understand the Kalman filter.)

WSNs consists of hundreds or thousands of low cost nodes

利用幂法求矩阵特征值，属于数值解法的一种(Using power method to find eigenvalues of matrices, which is a kind of numerical solution.)

说明：  偶图最大匹配完全照算法说明利用集合运算实现的matlab代码。这里需要大家讨论的是增广路的选取的算法，希望朋友们多多讨论，争取找一种更好的增广路方法，有想法的一定告诉我，谢谢，jxrhhu@hhu.edu.cn(Bipartite graph maximum matching algorithm description completely according to the use of computing to achieve a collection of matlab code. Here we need to discuss is the way to broaden the selection of the algorithm, a lot of friends who wish to discussions in order to find a better way to broaden the way, there is a certain mind to tell me, thank you, jxrhhu@hhu.edu.cn)
