线性相位FIR低通滤波器和48阶带通滤波器，并进行了比较的源程序。(Linear phase FIR low-pass filter and 48-order band-pass filter, and a comparison of the source.)

实现dsb、ssb和Am调制信号，很简单，可以在输入屏处按键控制(Achieve dsb, ssb, and modulated signals Am)

用MATLAB仿真雷达的函数，包括解调、混合、调制、PAM、PSK、及压缩编码等(Radar simulation using MATLAB function, including demodulation, mixing, modulation, PAM, PSK, and compression coding)

这是一个matlab编写的电离层误差图的程序。里边分别利用广播星历和模型修正进行了编程。(It is written in a matlab program ionospheric error plots. Inside were using broadcast ephemeris and model updating for the programming.)

The users in each cell are divided into cell-interior and celledge users. The categorization is based on the geometry factor and we take into acount the user distance its serving BS, considering a distance threshold Dth beyond of which the user is considered as cell-edge user.

蒙特卡洛算法也常用于机器学习，特别是强化学习的算法中。一般情况下，针对得到的样本数据集建立相对模糊的模型，通过蒙特卡洛方法对于模型中的参数进行选取，使之于原始数据的残差尽可能的小。从而达到建立模型拟合样本的目的。(Monte Carlo algorithm is also commonly used in machine learning, especially in reinforcement learning algorithm. In general, a relatively fuzzy model is established for the obtained sample data set, and the parameters in the model are selected by Monte Carlo method so that the residual error of the original data is as small as possible. Thus, the purpose of establishing the model fitting sample is achieved.)
