说明：  关于高层建筑强风条件下风压系数计算，整体风荷载评估(High-rise building on the strong wind conditions, wind pressure coefficients, the overall assessment of wind loads)

Simulink model of field oriented control. permanent magnet synchronous motor.

该资料详细介绍了MATLAB这款软件及一些入门知识，着重介绍了常用函数的使用等等，对初学者有很大帮助。(The information details the MATLAB software and some introductory knowledge of this, highlighting the use of commonly used functions, etc., are very helpful for beginners.)

MATLAB爬虫程序，获取指定时间段的所有上市公司公告文本。(A MATLAB spider can fetch the published texts by A-stock companies in certain period.)

说明：  bpsk仿真中间有两个方面的内容，很好的仿真软件(There are two files in the zip folder. bpsk_spread.m and jakesmodel.m Steps for simulation: 1] Run jakesmodel.m first 2] Then run bpsk_spread.m . 3] Note that during the first run bpsk_spread.m has no rayleigh fading.This is because the corresponding code has been commented 4] The resulting performance is stored in BER_awgn. 5] Now uncomment the Rayleigh Fading code in bpsk_spread.m file. 6] Same time comment BER_awgn (line 112) and uncomment BER_ray variable. 7] Run the simulation. )

Gaussian noise refers to its obey gaussian probability density function (i.e., normal distribution) of the noise. If a noise, its amplitude distribution obeys the gaussian distribution, and its power spectral density is uniformly distributed, has described it as a gaussian white noise. Were not associated with the second order moments of the gaussian white noise, a moment is constant, 所谓高斯噪声是指它的概率密度函数服从高斯分布（即正态分布）的一类噪声。如果一个噪声，它的幅度分布服从高斯分布，而它的功率谱密度又是均匀分布的，则称它为高斯白噪声。高斯白噪声的二阶矩不相关，一阶矩为常数，是指先后信号在时间上的相关性。高斯白噪声包括热噪声和散粒噪声。 (Gaussian noise refers to its obey gaussian probability density function (i.e., normal distribution) of the noise.
