已采集线性震动系统（钢板）的输入与输出（时域幅值），求解系统数值解，幅频特征，并作图比较。(Have been collected linear vibration system (steel) input and output (time domain amplitude), numerical solution for solving the system, the amplitude-frequency characteristics, and mapping to compare.)

In a multiple transmit antenna, single antenna per receiver downlink channel with limited channel state feedback, we consider the following question: given a constraint on the total system-wide feedback load, is it referable to get low-rate/coarse channel feedback from a large number of receivers or high-rate/high-quality feedback from a smaller number of receivers? Acquiring feedback from many receivers allows multi-user diversity to be exploited, while high-rate feedback allows for very precise selection of beamforming directions. We show that there is a strong preference for obtaining high-quality feedback, and that obtaining near-perfect channel information from as many receivers as possible provides a significantly larger sum rate than collecting a few feedback bits from a large number of users.

matlab上应用BP神经网络，预测人口、风速、温度。(Based on matlab, BP neural network to forecasting wind speed, temperature, populatioon.)

巴特沃斯滤波器设置，自行设置阶数、截止频率等滤波器参数(butter-worth filter)

这个是利用MATLAB实现的KNN算法的实现(This is achieved using MATLAB algorithm to achieve KNN)

改进的共轭梯度法，具有很好的收敛效果，达到整体最有，在MATLAB中实现。(Improved conjugate gradient method, has a good convergence effect, to achieve the overall most realized in MATLAB.)

MUSIC算法，波束域和阵元域都做了仿真并进行了对比！(MUSIC algorithm, simulation was made in the beam domain arrays and domain and compares the!)

冲击理论指的是计算结构响应的风动荡。这里,结构是一个吊桥,使用连续梁的理论建模。介绍模态耦合模型，尽可能的简单计算横向,纵向和扭转响应。结构的方法是使用。是专为那些已经拥有一些知识领域的随机振动分析和对结构风荷载。(The buffeting theory [1,2] refers to the computation of the response of a structure to wind turbulence. Here, the structure is a suspension bridge, modeled using the theory of continuous beam [3]. The frequency domain approach is used. I did not introduce modal coupling to keep the model as simple as possible. The present script computes the lateral, vertical and torsional response. A multi-modes approach is used. This script is designed for those who already have some knowledge in the field of random vibration analysis and wind loading on structures. )
