描述不同风速下风力机转速和功率之间的关系曲线(Describe the relationship between the speed and power of the wind turbine in different wind speeds curve)

说明：  一种基于运动模型的扩展卡尔曼滤波（EKF）算法,该方法适用于任何能用状态空间模型表示的非线性系统，精度可以逼近最优估计.(an EKF positioning and tracking algorithm based on kinematic model. This method can apply to any state-space model which is the nonlinear system, and the accuracy can approach to best of all. )

将彩色图像以RGB分为三层，使用直方图对其对比度进行调整，产生预定义的滤波器对图像进行滤波，最后实现图像的增强(RGB color image is divided into three layers, using the histogram to adjust its contrast, produce predefined filters for image filtering, image enhancement and finally realize)

matlab 和 simulink教程，很适用的(MATLAB_and_simulink_tutorial)

Differential PSK (DPSK) 􀂄 Inexpensive 􀂄 Quadrature Phase Shift Keying (QPSK) 􀂄 Twice as spectrally efficient than BPSK 􀂄 Offset QPSK (OQPSK) 􀂄 reduce envelope variation 􀂄 π/4 QPSK 􀂄 reduces envelope variations to a lesser extent than OQPSK can be noncoherently detected
