DigitalWidebandReceivers_second

说明：  用MATLAB仿真的数字下变频程序，变频，滤波未用matlab函数，而是用代码完成，便于移到DSP或FPGA上。供参考。(Using MATLAB simulation of digital down conversion process, conversion, filtering is not used matlab functions, but with code completion, easier to move on a DSP or FPGA. For reference.)

用互相关原理实现控制系统的频率特性测试仿真，供大家参考。谢谢！！(Using the principle of inter-related control systems achieve the frequency characteristics of the test simulation, for your reference. Thanks! !)

Its a saliency method by sombody ok.

calculating y-bus matrix of power system

说明：  标准25节点psat动态模型，包含模型描述以及simulink下搭建的模型(Standard 25 node psat dynamic model, including model descriptions and model structures under simulink)

说明：  完整的OFDM系统仿真程序，各个模块的组成！(Complete OFDM system simulation program, the composition of each module!)

实现循环卷积，个人觉得不错，传来大家一起分享！(convolution)

for fast optimize programming in matlab

I upload matlab code of Tracking servo system

costas环的matlab实现，该实现能够完成相位锁定，频率估计等动能(costas loop matlab implementation that can complete phase-locked, frequency estimation of the kinetic energy)
