摘要
本文推导了switched beam系统中干扰因子的计算式,以及中断概率、基站接收机灵敏度、移动台最大可允许的发射功率、信干比的期望值、路径损耗与小区覆盖半径、小区容量的关系式,并以直线天线阵为例,计算了小区容量和小区的覆盖半径。
The equation of interference factor for switched beam system, and a calculating method, which demonstrates the relationship between the outage probability, the sensitivity of the base station receiver, the maximum transmission power of the mobile station, the signal-to- interference ratio (SIR), the coverage radius of the cell and the capacity, have been presented. Some calculated results of the coverage radius and the cell capacity of a switched beam system with linear arrays have also been provided.
