无线通信系统中经典的功率控制注水算法Matlab实现。(waterfilling.m)

说明：  用于非线性时间序列分析的matlab代码，希望有人喜欢。NTSA是nonlinear time series analysis的简写。(For nonlinear time series analysis of the matlab code, I hope some people like. NTSA is a nonlinear time series analysis of shorthand.)

transducer design for ceramics pzt-4

OFDM 16QAM Simulink model

说明：  利用Esprit算法进行TOA估计，可用于无线传感器网络节点定位(TOA estimation by Esprit algorithm for wireless sensor network node localization)

当水下存在多个目标时，利用平均声强器检测已经不再有效，此时使用复平均声强器来确定多目标的方位。(When existing multi sources, average acoustic intensity does work. At this case, complex average acoustic intensity can obtain the direction of multi sources.)

说明：  当车辆通过时对车辆进行动态检测并用竖条线进行标记(When the vehicle passes through, the vehicle is dynamically detected and marked with vertical bar)

Zhang和Tan提出一个改良Niblack的方法(Zhang and Tan proposed a modified Niblack s method)

用于实现拉格朗日差值算法，可用于GPS星历计算(For the Lagrange interpolation algorithm, can be used for GPS ephemeris )

说明：  Matlab/Simulink中搭建卡尔曼滤波系统，可获得经滤波后信号。(A kalman filter system was built in Matlab/Simulink to obtain filtered signals.)
