主要面向工程设计人员，涉及的知识不但包括软件应用，还包括专业基础知识，是机械，电子领域技术人员的最佳参考书(Primarily for engineers, the knowledge involved, including not only software applications, including professional knowledge, machinery, electronics technicians the best reference books)

Multicarrier Modulation for Data Transmission: an Idea whose Time Has Come

ansys有限元分析软件的压电喷射模态分析适用于ansys (ansys piezoelectric transient)

最速下降法,是一种最优化的算法，针对无约束的优化问题有效(Steepest descent method, an optimization algorithm is effective for unconstrained optimization problems)

包括 MUSIC算法，ESPRIT算法 ROOT-MUSIC算法，分析了该信号的时域、频域、倒谱，循环谱等,esprit算法对有干扰的信号频率进行估计。( Including the MUSIC algorithm, ESPRIT algorithm ROOT-MUSIC algorithm, Analysis of the signal time domain, frequency domain, cepstrum, cyclic spectrum, etc. esprit algorithm signal frequency interference can be assesse.)

在matlab/simulink目前还没有更好地实现小波包模块，simuwave包括了各种各样的小波包子模块，可以自己实现小波分解。( At present, matlab/simulink is still not better to implement the wavelet packet module, simuwave includes a variety of wavelet packet module, you can realize the wavelet decomposition. )

说明：  绘制小提琴图，展示数据分布情况，非常实用的matlab数据可视化工具(Drawing violin diagram, displaying data distribution, very practical matlab data visualization tool)

阵列信号处理，前向平滑 原创啊。。。。。。。(Array signal processing, prior to the smooth original ah. . . . . . .)
