实现维纳滤波用于语音增强。第一步采用频域谱函数计算最佳的维纳滤波器，再对输入带噪信号进行滤波；第二步是在此基础上的改进，用了自适应的思想，及时根据当前帧的状态更新修正滤波器的系统函数，得到更精确的无噪语音信号。第三步是采用自适应LMS方法，在时域迭代计算滤波器系数，迭代次数足够多时可得到较准确的有用信号。(Implement wiener filtering used in speech enhancement. First step optimum wiener filter is obtained by using the frequency spectrum function, again to input the signal with noise filtering The second step is the improvement on the basis of this, with the idea of adaptive, and in a timely manner according to the current frame updates correction system function of the filter, get a more accurate without noise speech signal. The third step is to use the adaptive LMS method, iterative calculation in time domain filter coefficient, the number of iterations enough to get the useful signal accurately.)

汽车五自由度模型，当今很多悬架研究机构和科研单位运用各种软件对汽车悬架进行优化。MATLAB运用也越来越广，在汽车动力学研究当中起着重要作用。当然，汽车振动动力学仿真和分析也大量运用MATLAB/simulink模块。(Five degrees of freedom vehicle model, many of today s research institutions and research institutes in suspension using a variety of software to optimize the suspension on the car. MATLAB using more and more widely in vehicle dynamics studies which plays an important role. Of course, dynamic simulation and analysis of vehicle vibration also make extensive use of MATLAB/simulink module.)

有源噪声控制(ANC)主要基于LMS算法,但在处理宽带噪声信号和低信噪比情况下,效果不好.影响控制效果的主要原因是输入信号的自相关分布.而小波变换具有消除信号自相关的作用.因此将小波变换引入有源噪声控制(ANC)是解决问题的一种办法(Active noise control (ANC) is mainly based on the LMS algorithm, but ineffective in dealing with the situation of the broadband noise signal and low signal-to-noise ratio, the main reason affecting the control effect of autocorrelation distribution of the input signal. Wavelet transform to eliminate signalautocorrelation role Thus the wavelet transform is a problem-solving approach to the introduction of the active noise control (ANC))
