MATLAB实现的FSK-OOK-PSK-ASK仿真源码，想要的人来下(FSK-OOK-PSK-ASK)

有序样品的最优分割程序。本程序优点在于分类齐全，使用方便、直观。供大家学习参考。(ordered the optimal sample segmentation procedures. The classification process is complete advantages, easy to use, intuitive. We reference for the study.)

基于无速度传感器的异步电机调速系统，运用电流来合成磁链，控制方法是转子磁链定向。采用电流滞环控制，电网电压380V，转矩最大达30N.m。波形效果不错。(Based on speed sensorless induction motor speed control system, using current flux synthesis method for controlling the rotor flux orientation. Use current hysteresis control, grid voltage 380V, maximum torque of 30N.m. Waveform good results.)

利用MATLAB对SM4算法电路进行差分功耗分析攻击进行仿真，通过仿真可以实现对SM4加密算法的攻击。(it s the differential power analysis attack simulation for SM4 algorithm,which is realized in MATLAB language. From the simulation waves and results,the DPA for SM4 encryption algorithm is successful.)

一些循环平稳子程序，用于对循环平稳信号处理(Some Cyclostationary Subroutine, for cyclostationary signal processing)

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.)
