一些基于matlab/simulink的模型，以及s-function实现的网络控制系统模型，其中计算机、网络部分采用truetime模块！(based Matlab/Simulink model, and s-function achieving the network control system models, in which computers, network components using truetime module!)

It is a program for Quasi orthogonal space time block codes in Rayleigh fading channel

这个是我的毕业设计做的我觉得对大家还是有写用的，所以我给打击看看希望大家也给点意见。(this is my graduation design so I think people are still used to write, So, I hope to see you blow also points.)

pv three phase grid connected system

无线信息和能量同传的D2D通信，拉格朗日求解凸优化(D2D communication between wireless information and energy transmission)

This program plots spectrograms (vertical slices of intensities versus frequencies, with slices plotted against time).

Artificial Immune-Based For Voltage Stability Prediction In Power System

针对OFDM系统，分成链路级仿真和系统级仿真两个部分。为了降低系统级仿真的复杂度，采用链路级仿真的部分结果。(It contains mainly two parts, i.e. link-level simulator and system-level simulator. Link-level simulator focus on a single-cell single-user scenario, where signal is transmitted from tx, and estimated at rx. Comparing the difference in tx/rx signal, the error rate can be found out. The output of the link-level simulator is the BLER/BER vs. SNR mapping table, that can be used for the system-level simulation. System-level simulator focus on a multi-cell multi-user scenario. For the sake of simplicity, it takes the mapping table aquired in the link-level simulation, measure the actural SNR, and finds the corresponding error rate. Link-level simulator support SISO, 1 by x MRC, 2 by 1 STBC/SFBC, 2 by 2 Alamouti, x by 1 Antenna selection, x by y antenna selection. System-level simulator, currently support only SISO and 1 by 2 MRC. To start with, go into the folder sys_link_simu, and excute the following commond from matlab: sys_link_simu_func(a,b) where a is the link ada)
