| 摘 要： | 主要考虑中继接入选择策略对基于OFDMA的中继增强型蜂窝网络带来的系统性能影响.分别针对集中式和分布式控制两种情景,以最大化用户吞吐量为目标设计了基于信干噪比的接入选择策略.并通过搭建基于802.16j的系统级动态仿真平台对其性能进行仿真分析.与传统的接入方案相比.该方案在用户吞吐量分布,以及不同中继位置下的系统频谱效率指标下,均可获得更好的系统性能增益.

| Abstract: | The impact of the different relay choices on the OFDMA based relay-enhanced cellular network is investigated in this paper. A SINR-based access-point selection scheme is designed to maximize the per-user throughput,targeting respectively a centralized and a distributed scenario. To test system performance under such a scheme,a dynamic system level simulation platform according to IEEE 802.16j standard is established. Simulation results obtained from user through put distribution and the cell spectral effici... |
