摘要

在移动通信系统中

信干比作为评估信道质量的标准

可以用于功率控制场合

同时随着小区移动用户的增多

小区的裂化不可避免;两者的结合对信道容量将产生较大影响.本文将均匀小区的性能分析扩展到混合小区中

给出了利用信干比进行功率控制下混合蜂窝的反向链路容量的一般分析方法

数值计算结果表明

混合蜂窝中采用信干比进行功率控制

可以得到较高的信道容量.

Abstract

In the mobile communications system

the ratio of signal-to-interference used as a criterion of evaluating the signal quality

is adopted in power control.Also

in heavily populated areas

cell splits are unavoidable to increase the capacity of the cellular system.The reverse link capacity of an SIR-based power controlled cellular system with mixed cell is derived.The analytical results show that the system can increase the link capacity greatly.
