陆上移动通信场强预测

用个人计算机自动绘制场强地图的系统已经达到实用的程度。本系统先将地形和建筑物占有面积率等数据库建立起来,一旦对所要预测的地区输入收发信参数就能自动绘成场强地图。因而,效率、精度和可靠性会极大提高。同时,本文给出预测场强所用的一系列表达式。

Field Strength Prediction for On -Lend Mobile Communications

The system using personnel - computer to plot field strength maps automatically has been proved to be effective for practical purpose . It firstly sets up a database including the terrain and the occupied area ratio of the building . Once the parameters of trasmitting and receving ends are inputted to the computer , the field strength map of the area required to predict can be plotted automatically. Thus the efficiency , precision and reliability can be improved greatly . This paper shows a series of expressions used in the prediction of field strength at the same time .
