matlab coding for resource allocation

很实用的一个OFDM仿真程序，OFDM采用BPSK、QPSK、16QAM、64QAM4种调制方式。按照星座图，将每个子信道上的数据，映射到星座图点的复数表示，转换为同相Ich和正交分量Qch。(A very practical OFDM simulation program, OFDM the BPSK, QPSK, 16 qam, 64 qam4 kind of modulation method. According to the constellation diagram, each will be the data on the channel, the plural of constellation is mapped to a point, said into in-phase Ich and quadrature Qch. )

核密度估计的parzen窗法，简单易用，适合于初学非参数估计的用户。(Kernel Density Estimation parzen window method, easy to use, suitable for novice non-parametric estimation of the user.)

用MATLAB做公交换乘的代码（数学建模题）(Bus transfer to do with the MATLAB code (Mathematical Modeling title))

自己编的一个用随机行走法实现电路计算的例子，电路图及参数均在Partial random walk for large linear network analysis里(Own a random walk method used to achieve circuit examples, circuit diagrams and parameters in the Partial random walk for large linear network analysis in)

包含已提取过ROI的MSTAR的图像数据，可以用来作为目标识别的很好数据资源；包含傅里叶梅林变换提取不变特征的MATLAB程序(Containing the extracted image data of ROI MSTAR it can be used as a target to identify good data resources contains Fourier Mellin transform to extract invariant features of MATLAB program)

前向平滑的Root-MUSIC算法，可估计相干信源的波达方向(Forward smoothing Root-MUSIC algorithm to estimate the direction of arrival of coherent sources)

说明：  传染病模型是指传染病的基本数学模型，研究传染病的传播速度、空间范围、传播途径、动力学机理等问题，以指导对传染病的有效的预防和控制。常见的传染病模型按照传染病类型分为SI、SIR、SIRS、SEIR模型等。由于2019年末出现的新冠肺炎有一定的潜伏期，与病人接触过的健康人并不马上患病，而是称为病原体的携带者，归为E类。(infectious disease model simulation)
