The traditional power droop controllers are commonly used in distributed generation (DG) units to share the loads among the parallel inverters. However, the parameters of the power transmission and distribution line in microgrid are small and generally presented high resistance-to-inductance (R/X) ratio which will seriously influence the performance of the traditional power droop controller, even leading to instability

频率采样法设计高通FIR滤波器，结实得很详细。MATLAB代码。(MATLAB FIR )

说明：  OFDM中schmidl 的定时同步算法，包含不同信噪比下的性能(Schmidl in the OFDM timing synchronization algorithm, including the performance under different signal to noise ratio)

本软件包可以帮你安装东北大学六维空间的免费下载软件(This package can help you install the six-dimensional space, Northeastern University, free download software)

说明：  1 运行DCA_simuMain.m开始仿真 2 菜单：导入参数 --》 按键分配时隙--》输入BS编号，查看其最佳服务小区对应的用户，在matlab命令窗口可以看到其时隙分配情况(A simulation run DCA_simuMain.m Start Menu 2: Import parameter- &quot button allocated time slot-&quot input BS number, to view their best serving cell corresponding to the user, in the matlab command window you can see the slot allocation)
