QPSK

依据两个点的经纬度计算这两点在地球上距离的函数文件，误差很小(Calculated based on latitude and longitude of two points on Earth from these two points in the function file, the error is small)

神经网络对时间序列的观测时序进行预测，预测精度高，可以在工程上应用(Neural network to predict the timing of time-series observations, the prediction accuracy is high, can be applied in engineering)

这是根据点拟合圆和直线的matlab程序，比较简单实用(This is the basis of points won and a straight line fitting the matlab procedure is relatively simple and practical)

说明：  计算彩色图像的熵，均方误差,根据熵的技术公式，对彩色图像分RGB进行统计计算(compute the entropy and rmse of rgb image)

从网上看到了matlab实现的自适应中值滤波，用C++改写了一下。(Adaptive Median, matlab version to C++ version.)

这是一个关于舍此识别的一个matlab程序，可以识别舍此的位置。(This is a about the recognition of a matlab program that can identify the alternative location.)

dc-dc buck电路，仿真效果较好，偏差控制的很小，pi效果不错(DC-DC buck circuit, simulation effect is good, deviation control is very small, PI effect is good.)

说明：  蚁群算法的20*20km地图建模，及其三维路径规划(Ant colony 20 * 20 3D path planning)

灰色PID控制。灰色系统理论，PID控制。是灰色模型GM进行定量预测(Grey PID control. Grey system theory, a PID control. Grey model GM quantitative prediction)
