基于多跳中继的宽带接入网组网成本性能分析*

利用成本分析模型及等性能成本比较方法对基于多跳中继的宽带无线接入网络部署进行了量化分析，并与传统单跳网络部署进行了仿真比较。结果显示，基于中继的网络部署在保证性能的前提下能有效地降低组网成本，增强网络边缘吞吐量，扩大基站覆盖范围。进一步分析表明，无线资源配置方法也对网络的成本增益有一定的影响。复用技术能进一步改善中继网络的成本效益，并有效提升网络性能。

Cost performance analysis of multi-hop relay based broadband access network

This paper provided a qualitative performance assessment of relay based broadband wireless access network in comparison to traditional single-hop deployment. Used cost model and iso-performance curve to analyze and simulate the cost of network deployment. The results show that the deployment of relay can provide anopportunity to reduce the network deployment cost substantially, enhance the cell edge throughput and extend the cell range. The qualitative results further prove that the reuse of relay link between the RS and the BS will help to improve the cost efficiency of the relay based network deployment.
