unit converter in matlab

设计了一个扩频 系统，具有扩频解扩的功能。系统中采用的是瑞利衰落的信道。仿真的结果很好，系统的误码率很小(Designed a spread-spectrum system with spread spectrum despreading function. System is used in the Rayleigh fading channel. Good simulation results, the system bit error rate of the small)

说明：  实现演示程序！里面有很多关于程序的演示的源程序！(The demo program! There are many presentations on the program source code!)

A typical example of using the dSPACE system for electrical drives simulations is described in [9] and for wind energy conversion systems (WECS) in [10]. However, before the real-time implementation, the Control part has to be validated by simulation using a plant model. This model could be developed using either the Simulink transfer functions or the PLECS toolbox.

说明：  本程序用来求转子的临界转速，模型为有限元模型(This procedure is used to seek the rotor critical speed, the model for the finite element model)

This program reconstruct the mean temperature profile with the angle in the troposphere that is modeled with the program itself and needs the following functions: ariachiara,ariachiara2,nebbia,nebbia2,cirro,cirro2,pressione,nuvola,nuvola2,layer,layer2

对信号进行扫频，可以利用程序一次性读出所用频率的幅值和相位(Sweep the signal, you can use the program at once read out the frequency with amplitude and phase)

包括进行标准Hough变换，检测Hough变换中的n个峰值，并提取峰值直线像素点，绘制直线等(Including the standard Hough transform, Hough transform detection of the n-peak and peak extraction of straight-line pixels and draw a straight line, etc.)

PID极点配置控制（二阶系统，对象参数已知） (PID pole placement control (second-order system, the object parameters are known))
