应用于地铁车厢的可见光通信网络性能分析

open access: yesGuangtongxin yanjiu, 2018
针对室内可见光通信网络技术在地铁车厢等特殊场景下的应用问题进行了研究。基于光attocell网络概念,构建了一种适用于地铁车厢的小单元覆盖矩形网络结构模型,并充分考虑了用户受相邻单元光接入节点(AP)干扰的情况。为了提高单元边缘区域频谱效率,将直接部分频率复用和软频率复用方案应用到模型中。推导了网络的信干噪比累积分布函数及单元频谱效率闭式表达式,通过频谱效率对比分析评估了不同复用方案的网络性能。结果表明,边缘区域频率复用因子为2的方案性能最佳,能够有效地缓解边缘区域用户受临近单元AP干扰的程度 ...
