Spectral density, FFT, PSD,

说明：  此函数用于IS-95前向链路系统的仿真，包括扩 频调制，匹配滤波，RAKE接收等相关通信模块。 仿真环境: 加性高斯白噪声信道. 数据速率 = 9600 KBps (This function is used for IS-95 forward link system simulation, including the spread spectrum modulation, matched filter, RAKE receiver and other related communication module. Simulation environment: additive white Gaussian noise channel. Data rate = 9600 KBps)

说明：  对一个二阶模型模型进行脉冲响应辨识，并且通过搭建simulink模型取得了两组输入-输出数据，一组是在有高斯噪声的干扰下获得u1-y3，另外一组是在没有高斯噪声的情况下获得的u1-y1，对这两组数据进行基于haar小波基的脉冲响应辨识，与实际模型的脉冲响应相比较（注：三个excel表必须放在matlab/work文件夹下才能运行）(Second-order model to a model of impulse response identification, and achieved through building simulink model for two groups of input- output data, a Gaussian noise in the interference with access to u1-y3, another group in the absence of Gaussian noise of access to the u1-y1, these two sets of data haar Wavelet-based impulse response identification, and the actual model of the impulse response comparison (Note: Three excel table must be on the matlab/work folder to run ))

用来计算混沌动力学问题的源代码。包含分岔图绘制，最大李雅普诺夫指数，李雅普诺夫指数谱等一些重要的源程序。(This is a toolbox for chaotic dynamics analysis.Have fun!)

若干常微分方程求解问题的Matlab代码(Matlab code to solve Several ordinary differential equations problems )

matlab code for compressed sensing

9节点潮流计算采用的是牛顿拉夫逊法的直角坐标方法 采用的是matlab语言(power flow calculation 9 node)

合作是通訊的過程模擬仿真，有三種中繼的模式 可提供大家一個方向，謝謝(Relay Station Way)

线性调频信号的回波仿真，比较特别的是对近距目标的仿真(the stimulation of Linear fm signal wave , particularly to the close goals )

说明：  很好用 ， 实验过的， 素轻松判定素数数。(sushu)
