matlab在系统辨识中的应用此处为对具有随机噪声的二阶系统的应用的源代码及运行后结果（包括图像）(Matlab system identification in the application is right here for the second random noise of the system source code and running after the results (including images))

说明：  对VSC-HVDC系统进行暂态仿真，实现对VSC-HVDC系统的动态稳定性分析(Transient simulation of VSC-HVDC system)

频数统计，能够统计变量的出现的频数，还比较好用。(Frequency statistics, the statistical variables appear frequency, but also relatively easy to use.)

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.

Were not associated with the second order moments of the gaussian white noise, a moment is constant, refers to the correlation of signal in time. White gaussian noise including thermal noise and shot noise. )

基于matlab环境下的 绘制彩色玫瑰花的小程序 效果还是不错的 建议大家下载测试(Matlab environment based on the rose colored drawing or a good small program effects suggest that you download the test)

可用于3G/B3G系统当中的快衰信道的jakes模型的matlab仿真 作者已经将它用于ofdm系统 (3G/B3G system can be used for the rapid decline among Channel jakes model for the simulation of Matlab We have to use it for ofdm system)
