异步电机矢量控制仿真模型，采用间接磁场定向控制策略，电机模型没有采用matlab自带电机，而是根据两相旋转坐标系下的电机方程自己搭建了一个电机模型。(Induction motor vector control simulation model, using the indirect field oriented control strategy, the motor model comes with no motor using matlab, but according to the two-phase rotating coordinate system of the motor equations built himself a motor model.)

文件当中包含两个KALMAN滤波程序： 1.最原始简单的kalman滤波程序； 2.通过KALMAN滤波解决的一个派生例子（一道数字信号处理题）； 效果不错(Paper contains two KALMAN filtering procedures: 1. The most primitive simple kalman filtering procedures 2. KALMAN filter solution through an example derived (together with digital signal processing title) the effect of good)

This document shows in a simple way the near field of a dipole.You can choose the length of it.furthermore if anyone ask about this problem,please send a comment.

The software is capable to simulate space time code [1] for QPSK modulation using different number of state. Examples of generator matrix up to 256 stetes are provided. Variable signal to noise ratio (SNR) might be applied to produce bit error rate (BER) or frame error rate (FER) curves.(The software is capable to simulate space time code [1] for QPSK modulation using different number of state.
