Simulink中的开关磁阻电机的模型及其改进方法，希望大家指导 (The switch Simulink reluctance motor model and the improvement )

Some tips related to wireless channels

这里面有两个程序，两个都是采用4QAM调制。不过个人觉得第一个更容易懂，因为写的很有条理。我改的那个程序就是根据这个来的。 不过在这里面有个问题就是信道系数只能是由高到低，大家可以试试，改成[0.227 0.46 0.688 0.46 0.227]这个是老师给我的仿真中常用的信道系数，这个成为归一化信道，就是系数平方和为1. 第二个程序没有涉及到信道系数，但是这个程序当中，在128个子载波中，前后有32个空载波，这个在OFDM中也是经常用的，这样可以降低误码率。 (And there are two programs, two are based on 4QAM modulation. But personally feel that the first is easier, because the writing is organized. I changed that procedure is based on the past. However, there is a problem in that there is only channel coefficients from high to low, we can try and change into [0.227 0.46 0.688 0.46 0.227] This is the teacher gave me the simulation channel coefficient commonly used, this became normalized channel, is coefficient of the square and is 1. The second program is not related to channel coefficients, but this program which, in the 128 sub-carriers, the before and after the 32 air carriers, the in OFDM is also often used, which can reduce the error rate.)

曲线标记，设计与所画曲线中标记为圆形星形，或其他形状，方便读者识别(Curve marked)

说明：  matlab 和c或者c++ 接口程序，采用mex技术和matlab 计算引擎方式，可以提高matlab运行效率(matlab and c or c++ interface program using matlab calculation mex engine technology and methods can improve the operating efficiency matlab)

说明：  关于码matlab的介绍，对于初学者来说能够很快了解matlab。(On the introduction of matlab code, for beginners to quickly understand the matlab.)

Matlab工具箱 - 《复分析基础及工程应用 第3版》，这是书中所带工具箱，与Matlab本身的复分析工具箱相背相比，更适用于教学。(Matlab Toolbox- Fundamentals of Complex Analysis with Applications to Engineering and Science the 3rd version,compared with the similar toolbox of matlab,this toolbox is good at teaching.)
