摘要：

针对室内复杂的无线传输环境和较大的吞吐量要求，该文提出在室内场景中部署中继以提升吞吐量和覆盖范围，并对大型室内场所的无线传输环境进行建模，改变其中的参数以适应不同的实际环境. 以大办公室环境为例，提出一种室内中继部署和优化方案及其仿真方法，根据对系统性能需求的预测求得各接入点的部署数量、位置和中继工作模式. 仿真结果表明，在室内环境中部署中继可有效提高系统吞吐量和覆盖面积. 综合考虑系统性能要求和网络成本，使用1 个基站和4 个放大-转发中继站共同覆盖为理想的网络部署方案.

Abstract:

To deal with complex indoor wireless environments and high throughput requirements, deployment of indoor relay networks is investigated. A mathematical model is established for large office buildings, with adaptively changed parameters are adaptive to meet the practical conditions. As an example, relay network deployment in an indoor scenario with a large local environment is considered. With the proposed model, the number of access points, the locations of deployment, and the selection of relay work modes are derived based on the system performance requirements. The simulation results show that deploying relay stations in the studied environment can effectively improve the system throughput and coverage. Taking both systemperformance and network-cost into account, one base station and four amplify-forward relay stations can form an ideal deployment.
