摘要

首先在两跳中继CDMA蜂窝系统的基础上

提出了2种使用带外信道提高传统CDMA蜂窝系统上行链路容量的中继方法;然后通过分析传统无中继CDMA蜂窝系统的干扰功率

分别得到这2种中继方法对当前小区和邻居小区总的干扰功率;最后在一种对称小区模型的基础上

通过数值计算对两跳中继CDMA蜂窝系统的上行链路容量进行分析

并讨论了2种中继方法对系统性能所产生的影响。

Abstract

Based on the two-hop-relay CDMA cellular systems

two kinds of out-of-band relaying methods were pro-posed to improve the conventional CDMA cellular systems.Then by analyzing the interference power of the non-relaying CDMA cellular systems

the overall interference power to own and neighbor cell could be obtained with using these two relaying methods.Finally

based on a symmetrical cell model

the uplink capacity of two-hop-relay CDMA cellular sys-tems was analyzed by mathematical calculating

and the impact of these two relaying methods on system’s performance was discussed.
