宽带无线信号的多径效应仿真，外文教材的代码(Broadband wireless signals in multi-path effects simulation, foreign language teaching materials code)

说明：   Buck－Boost电路的建模与仿真主程序

系统介绍通信网，包括通信网信源模型，erlang拒绝和等待系统，通信网性能分析(system introduced communications network, including communications network source model, and refused to wait for the erlang system performance analysis of communication networks, etc.)

The ant algorithm matlab simulation(The ant algorithm matlab simulation )

一些Optisystem软件的仿真例子，通过这些例子学习可以轻松上手，适合从事光纤研究人员。(some examples for Optisystem)

利用双线性Z变换设计巴特沃斯和切比雪夫I型IIR数字滤波器，包括低通、高通、带通、带阻四种形式。使用者只需指定通带、阻带的边缘实际频率及相应的衰减，便可输出数字滤波器 的级联形式的各子系统分子、分母的系数，并输出其幅频和相频响(Bilinear Z transform design Butterworth and Chebyshev Type I IIR digital filters, including low pass, high pass, band pass, band stop four forms. Users simply specify the passband edge frequency stopband actual and corresponding attenuation subsystems can form molecular cascade output digital filter coefficients of the denominator, and the output of its magnitude and phase frequency response)

内容：空间目标识别，采用PM算法。程序中附有注释，可以改变方向角，运算速度比music算法快，本人毕设程序，绝对可用。(Content: space target recognition using PM algorithm. Annotated program, you can change the direction of the angle calculation algorithm is faster than the music, I set up the program, absolutely free.)

说明：  该code读出naca4412.txt中基本balde坐标，在读取data1.txt中设计要求，生成FinalCoordinates.txt文件，包含所有生成balde airfoil所需coordinates。(this matlab code read the blade coordinates in naca4412.txt, and then read the design requirements in data1.txt. Finally, it will generate the FinlCoordinates.txt which include all the coordinates of blade airfoil.)

利用MATLAB进行铅垂平面无控弹道仿真，并给出一些参数的变化图像(Vertical plane with MATLAB uncontrolled trajectory simulation, and give some parameters change image)

四阶累积量ESPRIT方法仿真讨论，很实用。(ESPRIT method for fourth-order cumulant simulation discussion, it is practical.)
