matlab 数字实验， 关于数字信号处理课程matlab的数字实验。(matlab digital experiments on digital signal processing matlab figures experimental courses.)

说明：  基于MATLAB/GUI的M-QAM调制解调及误码率,本文件是在MATLAB2009a版本上设计的，低于此版本的有可能会出错。 此文件中“M_QAM.m”是主文件，其他均为调用文件,该程序实现了MQAM的调制解调功能，并画出了每一步的波形 (Based on MATLAB/GUI s M-QAM modulation and demodulation and bit error rate, this document is designed MATLAB2009a version, this version is lower than might be wrong. This file is in the " M_QAM.m" is the main document, others are calling the file, the program implements the MQAM modulation and demodulation functions, and draw the waveform of each step)

利用自抗扰控制器理论，提出了一种新颖的永磁同步电动机无位置传感器矢量控制系统 的转速估计方法。(A novel speed estimation approach to sensorless vector control of Permanent Magnet Synchronous Motor (PMSM) based on Active Disturbance Rejection Controller (ADRC) was proposed. )
