说明：  mimo系统中相关多波束仿真方法，希望对大家有帮助(MIMO system related Multibeam simulation method, we hope to help)

The following attachment contains codes in Matlab for digital signal processing. In the file codes is to analyze the symmetry of digital signals

Analysis of Multiple-Input-Multiple-Output (MIMO) System with Transmit and Receive Diversity

说明：  lm算法的matlab程序，自己编的，不是库函数(lm algorithm matlab procedures, own, and not a library function)

该源码来自教程＜先进的pid控制及matlab仿真（第一版）＞，对初学者非常有帮助.(The source code from the tutorial <advanced pid control and matlab simulation (first edition)>, very helpful for beginners.)

无线衰落信道之瑞利衰弱的仿真 可以做出多径瑞利的仿真 (Simulation of Rayleigh weak)

人耳滤波器 Gammatone带通滤波器(Gammatone filter)

将PID 控制与模糊控制的简便性、灵活性以及鲁棒性融为一体,构造了一个参数自整定模糊PID 控制器. 通过模糊控制规则在线调整PID 控制器的参数,并利用MATLAB 语言结合具体实例方便而快速地实现了该控制器的计算机仿真. 仿真结果表明:该控制方法提高了控制系统的动、静态特性,使系统获得了较好的性能.(The PID control and fuzzy control of the simplicity, flexibility and robustness of the integration, construction of a parameter self-tuning fuzzy PID controller. Through the fuzzy control rules online adjust the parameters of PID controller, and use specific examples of MATLAB language and quickly realize the convenience of the controller)

研究生期间完成的有源电力滤波器仿真（APF）,采用电流内环，电压外环的双闭环控制方案。同时，交流测滤波电感经过了精心设计，滤波效果很好。(Graduate students during the simulation of active power filter (APF), the completion of the current loop, double closed loop control scheme of voltage outer loop. At the same time, the AC side inductance by design, a very good filtering effect.)
