【摘要】 根据几何绕射理论的建模思想 ,利用MATLAB语言 ,对自由空间的电波在高层建筑物后的传播路径损耗和场强的分布进行了仿真和计算 ,并用图形和不同的颜色来表示场强的强弱分布 ,对无线电基站的选址定位起到了很好的辅助效果 .更多还原

【Abstract】 Based on the model of geometrical diffraction,with the MATLAB language,the path loss of radio wave during propagation behind the high buildings is simulated.The distribution of field strength is displayed with different color.This is helpful for selecting location of radio bases.更多还原
