Reduction of Craig_Bampton(this is a method of reducing Finite Element Method)

Locally linear embedding(LLE)是一个经典的流形学习降维方法，通过LLE发现高维数据潜在的内在维数，可以简化计算、方便可视化处理等。(Locally linear embedding (LLE) is a classic manifold learning dimensionality reduction method, discovered by LLE potential inherent high dimensional data dimension, the calculation can be simplified to facilitate visual processing.)

基于chebyshev的水声信号分析，能量熵的计算，数值分析的EULER法，处理信号的时频分析，FMCW调频连续波雷达的测距测角，使用大量的有限元法求解偏微分方程，预报误差法参数辨识-松弛的思想。( Based chebyshev underwater acoustic signal analysis, Energy entropy calculation, EULER numerical analysis method, When processing a signal frequency analysis, FMCW frequency modulated continuous wave radar range and angular measurements, Using a large number of finite element method to solve partial differential equations, Prediction Error Method for Parameter Identification- the idea of relaxation.)

应用差分方程求解波动方程，可以设定边界条件(Application of differential equation solving the wave equation, boundary conditions can be set)

作为一个有吸引力的技术， 减轻多径干扰的正交频 分复用（OFDM）已经被广泛应用 在各种广播系统，诸如数字 视频广播（DVB）系统。尽管它的竞争力 属性，OFDM信号的特点是非常高的 峰值对平均功率比（PAPR）的水平。( As an attractive technique in mitigating the multipath interference, Orthogonal Frequency Division Multiplexing (OFDM) has been widely applied in various broadcasting systems such as, the Digital Video Broadcasting (DVB) systems. Despite its competitive attributes, OFDM signals are characterized by very high Peak-to-Average Power Ratio (PAPR) levels.)
