说明：  能够很好的实现混沌数字水印技术 并且具有创新功能 (Can achieve the chaotic digital watermarking technology and innovative features)

QPSK调制后产生QPSK信号，QPSK信号分别通过AWGN信道、Rayleigh衰减信道和Rician衰减信道，分别通过QPSK解调出数字信号，通过输入与输出数字信号的对比计算出仿真过程中的传输误比率，并将其与各衰减信道的理论误比率进行对比(Generate QPSK signal QPSK modulation, QPSK signals through AWGN channel, Rayleigh fading channel and Rician fading channel, respectively, through the QPSK demodulation of digital signals by comparing input and output digital signals to calculate the simulation process of transmission error rate, and to compare with the theoretical error rate for each decay channel)

分别对速度、磁场两个分量进行独立控制。通过控制转子磁链，以转子磁通定向，然后分解定子电流而获得转矩和磁场两个分量，经坐标变换，实现正交或解耦控制(The velocity and magnetic field components are controlled independently. By controlling the rotor flux, the rotor flux is oriented, and then the stator current is decomposed to obtain two components of the torque and magnetic field. Orthogonal or decoupling control is realized by coordinate transformation.)

matlab程序运行时导入数据文件作为输入参数，部分实现了追踪测速迭代松弛算法，FIR 底通和带通滤波器和IIR 底通和带通滤波器，用于特征降维，特征融合，相关分析等,多抽样率信号处理，搭建OFDM通信系统的框架。

该程序是子空间在盲点估计的应用，开发环境是MATLAB，对学习子空间辨识算法的很有用！(The program is estimated that sub-space in the blind spot of the application development environment is MATLAB, on learning subspace identification algorithm is useful!)
