论文摘要
在本文中，我们使用波长多访问（WDMA）方案研究了用户分布对可见光通信（VLC）系统中资源分配的影响。在这项研究中，检查了两种不同的房间布局。考虑了三种10用户方案，而使用四个面的光学角度多样性接收器（ADR）。在每种情况下，使用混合刻板线性编程（MILP）模型来识别最佳波长和接入点（AP）分配。结果表明，用户分布的变化会影响通道带宽和SINR的水平。但是，与群集用户相比，房间中用户的统一分布可以为所有用户提供更高的频道带宽，而高于阈值（15.6 dB）的高sinr（15.6 dB），这是一种具有最低SINR的情况，其支持数据速率最低，而支持的数据速率高于3.2 Gbps。
In this paper, we investigate the impact of user distribution on resource allocation in visible light communication (VLC) systems, using a wavelength division multiple access (WDMA) scheme. Two different room layouts are examined in this study. Three 10-user scenarios are considered, while an optical angle diversity receiver (ADR) with four faces is used. A mixed-integer linear programming (MILP) model is utilized to identify the optimum wavelengths and access point (AP) allocation in each scenario. The results show that a change in user distribution can affect the level of channel bandwidth and SINR. However, a uniform distribution of users in the room can provide a higher channel bandwidth as well as high SINR above the threshold (15.6 dB) for all users compared to clustered users, which is a scenario that has the lowest SINR with supported data rate above 3.2 Gbps.
