matlab下对于系统模型的仿真，为复杂系统设计做准备(matlab simulation model under the system, in preparation for the design of complex systems)

说明：  matlab source code for dsp

this file calculate reactive power of 39 buses ieee standard system with pso algorithm

用MATLab仿真了基于矩量法的V形阵子天线的方向图和天线上的电流分布图(With MATLab simulation time around based on the method of moments of the V-shaped antenna pattern and antenna current distribution)

程序对2发2收系统进行SVD算法的仿真。发送信号采用QPSK调制，信道为准静态瑞利平坦衰落信道，引入的噪声为均值为0的高斯白噪声，接收端采用最大似然检测算法，仿真其误比特率特性。(The SVD algorithm simulation program 2 admission system. Send signals using QPSK modulation, channel prevail static Rayleigh flat fading channels, the introduction of noise with mean 0 Gaussian white noise, the receiving end using the maximum likelihood detection algorithm, simulation of the bit error rate characteristics.)

Overview: In the application, often the need for custom report format, such as the printing contract, cargo manifests,

说明：  计算直流潮流的算法，基于MATLAB，忽略无功功率，只考虑有功功率。(DC Power Flow Algorithms)

这是EMD的程序吧，里面的子程序也重新整理好的，本人已经调试成功！(This is the EMD program,it contains the subcode and I have debugging it sucessfully)

说明：  MIMO系统的功率优化问题，通过SVD分解和注水算法，可以实现不同发送天线上的功率分配。(MIMO system power optimization problem, and through the decomposition of water injection SVD algorithm can achieve different this antenna on the power distribution.)

HHT就是先将信号进行经验模态分解（EMD分解），然后将分解后的每个IMF分量进行Hilbert变换，得到信号的时频属性的一种时频分析方法。(HHT is the first signal empirical mode decomposition (EMD decomposition), and then each IMF component decomposed Hilbert transform, frequency analysis method of time-frequency properties obtained when a signal.)
