数字滤波技术是在干扰通过输入通道进入计算机后的一种软件抗干扰的补救办法。 (Digital filtering technology interference in through the input channel into the computer after a software anti-interference remedy.)

capon波束形成器，也称MVDR波束形成器。 它试图使噪声以及来自非θ方向的任何干扰所贡献的功率为最小,但又能保持在观测方向θ上的信号功率不变(capon beam form)

说明：  Isomap通过“改造一种原本适用于欧氏空间的算法”，达到了“将流形映射到一个欧氏空间”的目的。(Isomap achieved the goal of "mapping manifolds to an Euclidean space" by "reforming an algorithm that was originally suitable for Euclidean space".)

对leach算法进行仿真，主要是leach的分簇路由算法(Algorithm is simulated on the leach. the main is cluster routing algorithm )

说明：  matlab 通用神经网络代码,较全面，好不容易找到的。(common neural network matlab code, a more comprehensive, not easy to find.)

经典窄带信号含有两个干扰源，最后绘制方向图(Classic narrowband signal contains two sources of interference, the pattern drawn last)

LMMSE performance analysis

this gives you detailed abt the active power filter and its used. You can mitigates the harmonics by using a active power filter.

计算振动信号的Choi-Williams分布，通过对照轴承故障特性频率可知，轴承的外圈发现了故障，完成了对外圈的故障特征提取。(The Choi-Williams distribution of the vibration signal is calculated. Through the comparison of the bearing fault characteristic frequency, the outer ring of the bearing is found to be faulty.)

经验模式分解程序（matlab）可以对输入信号进行经验模式分解(Empirical mode decomposition process (matlab))
