本文提出了一种新的、且易被人接受的移动无线电系统的参数设计方法。在系统规模结构、制式确定后求取基地台一些参数(发射机功率、天线高度)是通过对整个系统区域地形抽样块场强的反复预测而得。然后,根据通信质量的要求,求得频率再用间隔、三阶互调干扰距离。而系统最佳信道配置数的求取是利用系统话务量和系统特征模拟的方法,经过多次调整信道数,反复模拟而得。 本文给出了带状系统和小区制系统的设计实例。
This paper presents a new and easily accepted parameter design method for mobile radio systems. In the system size structure, the formula to determine the base station to determine some of the parameters (transmitter power, antenna height) is obtained by the entire system area terrain sample block field strength repeatedly predicted. Then, according to the requirement of communication quality, find the frequency reuse interval and the third-order intermodulation interference distance. The optimal number of system channel configuration is calculated using the system traffic and system characteristics of the simulation method, after repeated adjustments to the number of channels, repeated simulation derived. In this paper, the design examples of strip system and cell system are given.
