给音乐添加噪声再通过低通滤波器滤掉噪声，性能改善过后能明显看到效果。(Add noise to the music and through a low pass filter filters noise, performance improvement can be evident after the effects.)

matlab的nmf工具箱，很有用。希望大家下载拥有。(nmf the matlab toolbox, useful. Hope you have downloaded.)

matlab结构数组观测程序 可在Gui看结构数组的内容(Matlab structure array observation process will be Gui look at the contents of the array structure)

噪声语音信号的处理。能够事项语音信号的自动去噪处理。效果良好。是M文件。语音信号要自己录制。( The noise speech signal processing. Automatic speech signal denoising. The effect is good. Is the M file. The speech signal to be recorded. The noise speech signal processing. Automatic speech signal denoising. The effect is good. Is the M file. The speech signal to be recorded. )

说明：  通信仿真及实例详解。对matlab学习者很有帮助啊(communications simulation and example explanation. Right Matlab learners helpful ah!)

小波包分析提取振动信号中的特征频率，IDW距离反比加权方法，包括随机梯度算法，相对梯度算法。( Wavelet packet analysis to extract vibration signal characteristic frequency, IDW inverse distance weighting method, Including stochastic gradient algorithm, the relative gradient algorithm.)

说明：  异步电机的精确控制和速度辨识是交流传动系统中重要问题。在该仿真系统中，电机转速采用易于检测的电机定子电压和电流得到转速MRAS辨识算法来估算。由于速度辨识算法中电压模型的纯积分环节会引起的误差积累和漂移问题，采用改进积分型转子磁链估算模型来解决。(The precise control and the speed identification of AC motor are the very important issues on AC drive system.In this system, induction motor is controlled by the direct torque control, stator flux is estimated by u-n model observer that is effective in the full range of speed, motor speed is estimated by MRAS speed identification algorithm that is depended on the voltage and the current of motor stator easily detected. The modified integral rotor flux estimation model is used to solve the problem that the normal model can be affected by the error accumulation and drift of integral calculation in the voltage model of conventional speed identification algorithm. )
