摘要
构建了一种基于OFDM非竞争的频带内多跳系统,提出并对比分析了两跳中继网络的配置方案,研究了两个中继方案中多跳回程网络和接入网络的资源分配问题。在带内中继回程网络和接入网络共享同一个无线资源的条件下,通过计算分析和静态的系统级仿真方法,揭示了两种中继方案的无线资源分配结果与小区覆盖范围和信道状态的关系。
A non-contention in-band multi-hop system based on OFDM was built. Two configurations of two-hop relay network were proposed and comparatively analyzed. The resource allocation issue between multi-hop backhaul network and access network was investigated. The relay backhaul network and access network share the same resource. By using calculation and a static system level simulation, the relationship among resource allocation results of the relay schemes, cell coverage and channel status was revealed.
