总结了自己关于通信原理学习的一下认识,希望大家多交流(about Communication Fundamentals in my side)

以天线方向图函数为例，分析了对称阵子天线、阵列天线方向图函数F(0， )随各参量变化的规律以及二维图形的特点，并讨论了直线天线阵(单向端射阵)的最大辐射方向和主瓣宽度随各参量变化的二维、三维图形特点。借助MATLAB的绘图功能，对各种天线的方向图函数的二维、三维图形进行研究，可以观察到天线辐射场在不同方向的辐射能量分布。直观清楚地表现出辐射方向图的特点。(Antenna pattern functions as an example to analyze the symmetry time around antenna array antenna pattern function F (0,) with each variation of parameters and characteristics of two-dimensional graphics, and discussed the linear antenna array (one-way end-fire array) The maximum radiation direction and the width of the main lobe of each parameter change with 2D and 3D graphics features. With MATLAB graphics functions for 2D and 3D graphics in a variety of antenna pattern function were studied, the antenna radiation field can be observed in the distribution of radiation energy in different directions. Features an intuitive clear demonstration of the radiation pattern.)

本算法用来实现图像的首数字规则特性，首数字规则在1881年就被发现，他能检测图像的所有像素点的AC系数是否符合首数字规则(The first algorithm is used to achieve image characteristic figure rule, the first rule number 1881 was found that he can detect all the pixels in the image whether the First Digital AC coefficient rules)
