说明：  实现QPSK位同步G算法，方法很经典，可以查看小数u和误差变化(Gardner matlab The QPSK bit synchronization g algorithm is implemented. The method is very classical, and the decimal u and error change can be viewed)

说明：  本程序仿真了电子扫描阵列天线方向图，实现了不同参数情况下栅瓣现象、主瓣宽度和功率增益随扫描角变化情况(This program simulates the electronic scanning array antenna pattern, and realizes the change of grating lobe phenomenon, main lobe width and power gain with scanning angle under different parameters.)

模拟gps信号的产生，基本功能已经实现，没有问题(sample qt)

DOP计算源代码，给出了详细的计算方法和公式(DOP calculation of the source code, gives a detailed calculation methods and formulas)

说明：  较新的优化算法，麻雀算法优化BP神经网络权值与阈值；(the key parameters of BP are choosed automatically by Sparrow Search Algorithm.)

说明：  所有有关DOA估计的程序和代码，相当于一个完整的工具箱(All programs and codes related to DOA estimation are equivalent to a complete toolbox.)

说明：  用人工势场算法结合模糊控制算法的路径规划(Path planning with artificial potential field algorithm and fuzzy control algorithm)

说明：  水声通信网移动节点定位误差分析，主要描述了位置为节点相对于固定节点的位置变化(Positioning error analysis of mobile node in underwater acoustic communication network)
