This paper presents a topology design scheme (HeteTopo) for QoS-based heterogeneity ssues in overlay multicast. The scheme aims at constructing a topology tree with differentiated QoS support for heterogeneous multicast service while optimizing the related tree cost metrics

利用最小二乘法的原理高精度估计正弦波信号的幅值，频率和初相(The principle of using the least squares method estimated sine wave signal amplitude, frequency and initial phase of high-precision)

这是脉象信号的处理数据，可以得出最佳取脉压力，是很好的处理程序(This is the pulse signal processing data, we can draw the best to take the pulse pressure is a good handler)

一个很完美的解决数据关联问题中坐标转换的文章(A perfect solution data associated coordinate transformation article)

Assume that a direct sequence spread spectrum system uses the Barker code of length 7 (N=7) as its spreading sequence. a. Randomly generate 8 symbols (d0~d7) from the set {+1,-1}. b. If each chip of the Barker code is denoted as cj, j=0~6, spread each symbol di by the Barker code. (Please refer to p. 17 of the slides.) Use “stem” to plot the signals before spreading and after spreading
