针对正弦信号的PID响应进行控制，系统采用基于S函数的simlink仿真。(In view of the sine signal response to the PID control, the system adopts simlink simulation based on S function.)

在仿真中，我们规定每个移动节点的发射功率是常数，PTx = 1W；接收节点接收机的灵敏度Smin = -80 dBm；信号质量 min = 2 dB；系统的背景噪声门限INThre = 1.2e-10(In the simulation, we require that each mobile node s transmission power is constant, PTx = 1W receiver node receiver sensitivity Smin =-80 dBm signal quality )

使用鏡子鏡射的原理，也就是將接收點鏡射之後，求取傳送點與接收點的距 離，而因為公式(1)及公式(8)，可知角度與距離有關係，可以使用這個公式來直 接代入公式(10)之中。(. The receiver is located at the center of a 50-m*50-m room and transmitter is moved along a straight from 2m to 20m from the receiver. Show the received power in decibels versus distance for the LOS path, and include all the first-, second-,third-order reflections. (Gt = Gr = 1.6, f = 1GHz, a =-0.7, Pt = 1W))

Keogh的SAX聚集近似算法，首先采用PAA分段，然后正态化序列，在对应表上查询符号表示，这是一个很经典的时间序列表示方法(Keogh' s SAX gathered approximation algorithm, the first use PAA segment, then normal sequence, query on the corresponding symbol table indicates, this is a classic representation of the time series)
