传统的DOA估计算法，如MUSIC、ESPRIT算法，都是在假设信号没有相干的情况下求解的，一旦信源信号具有相干性，估计性能会急速下降，所以提出了空间平滑的算法，解决相干信号的波达估计！(The traditional DOA algorithms, such as MUSIC, ESPRIT algorithm, is under the assumption that the signal is not coherent case solving, once the source signal with coherence, estimation performance will fall, so put forward spatial smoothing algorithm, to solve the coherent signal estimation of direction of arrival!)

说明：  Fresnel 衍射的计算，光学衍射的实例，可参考(Calculation of Fresnel diffraction, optical diffraction of the examples, reference may be)

学习MATLAB的入门级教材，内容包括“向量与矩阵”、“绘图与图形”、“统计与MATLAB编程介绍”、“代数方程求解与其他符号工具”、“基本符号运算与微分方程”、“ODE的数值解”、“积分”、“变换”、“曲线拟合”、“使用特殊函数工作”。(It could guide you into MATLAB programing if you didn t even learn it. )

可实现微电网中分布式电源的下垂控制，采用三环控制策略，节点既可作为V/f结点，也可作为PQ结点(It can achieve distributed generation droop control in Microgrid, which uses three-loop control strategy. The node can be used as V/f node, the node can also be used as PQ node)

通过比较循环相加法和重叠保留法的性能，使用重叠想加法来进行音频信号的去噪(Overlap-add and overlap-save method is a method of two methods used to seek a finite sequence of linear convolution. Through performance comparison of the two methods, select the overlap-add method de-noising experiments )

说明：  通过NLMS算法实现信号的时域信号时延估计(Time domain signal delay estimation based on NLMS algorithm)
