移动的蜂窝网络上的高数据速率服务的增长需要更有效地使用可用的有限带宽/功率资源。理想情况下，这应该以最少的额外基础设施来实现，因为它在资本支出和网络重新设计方面都是昂贵的。其中一条目前引起人们极大兴趣的进化路径是多跳。该方案使用一个或多个中继来转发基站（BS）和目标用户设备（UE）之间的传输。给定足够大的中继密度，在BS和目标UE之间将总是存在比直接跳路由更有路径损耗效率的多跳路由。然而，这将如何转化为小区吞吐量和覆盖范围的可实现的改进并不那么明显。多跳的实际益处取决于许多关键系统选择，诸如调度算法和所使用的天线阵列处理的类型。本文认为，通过模拟多跳的好处如何不同的系统，采用组合的轮询或等吞吐量调度与2或4个元素的最大比率组合。版权所有© 2007约翰威利父子有限公司.
The growth of high-data rate services on mobile cellular networks necessitates more efficient use of the finite bandwidth/power resources available. Ideally this should be achieved with minimum additional infrastructure since it is expensive both in terms of capital outlay and also network redesign. One such evolutionary path which is currently fuelling a lot of interest is multi-hop. This scheme uses one or more relays to forward transmissions between the base station (BS) and the target user equipment (UE). Given a large enough density of relays, there will always be a more path loss efficient multi-hop route between the BS and target UE than the direct hop one. However, it is not so obvious how this will translate into realizable improvements in cell throughput and coverage. The actual benefits of multi-hop are dependent upon a number of key system choices such as the scheduling algorithm and type of antenna array processing used. This paper considers through simulation how the benefits of multi-hop vary for systems that employ combinations of round robin or equal throughput scheduling with either 2 or 4 element maximal ratio combining.
