matlab下编写的谱相减函数，用作语音增强(prepared under matlab spectral subtraction function, used for speech enhancement)

此为我老师写的RGELS算法，适合系统辨识的初学者(This is my teacher wrote RGELS algorithm, suitable for system identification of the beginners)

说明：  这是双馈电机的矢量调制方法的仿真，仿真效果还可以。(This is doubly-fed vector modulation method of simulation, the simulation results can also.)

基于 BPSK QPSK 16QAM 各种调制方式的matlab仿真代码(Based on a variety of BPSK QPSK 16QAM modulation matlab simulation code)

The function generates CA codes for all 32 satellites based on the settings

说明：  一个实现hilbert变换的小程序包，程序写得很简明，对理解hilbert变换的实现过程很有帮助(Hilbert transform an implementation of small packages, programs written very concise and to the understanding of the implementation process is helpful hilbert transform)

It has m files. These m files will run in matlab. Different kinds of table can be drawn by these m files

一个三角形单元的有限元程序简易算例，最后可用输出tecplot打开的云图文件.plt(A triangular element of the finite element program simple example, the last available output tecplot open cloud file .plt)

信噪比从0～13 dB，每隔1 dB仿真得到二进制双极性码的误码率(The bit error rate of binary bipolar codes is simulated every 1 dB from 0 to 13 dB.)

利用自然梯度算法，ML法能够很好的估计信号的信噪比,考虑雨衰 阴影 和多径影响。( Use of natural gradient algorithm, ML estimation method can be a good signal to noise ratio, Consider shadow rain attenuation and multipath effect.)
