论文摘要
光学无线通信（OWC）系统已成为一种有希望的无线通信技术，可以同时提供高数据速率并支持多个用户。在本文中，当使用波长多重访问（WDMA）与角度多样性接收器（ADR）结合使用时，研究了房间大小的影响。根据所使用的RYGB LDS发射器，可以在这项工作中提供四个波长（红色，黄色，绿色和蓝色）。考虑了三个房间尺寸，具有两个8用户场景。为优化资源分配的目的，提出了混合企业线性编程（MILP）模型。在所有房间的两个情况下，已经计算了每个用户的光通道带宽，SINR和数据速率。与其他房间相比，A房间是最大的房间，可以提供更高的通道带宽和SINR。但是，在两种情况下，所有房间都可以提供高于5 Gbps的数据速率。
Optical wireless communication (OWC) systems have been the subject of attention as a promising wireless communication technology that can offer high data rates and support multiple users simultaneously. In this paper, the impact of room size is investigated when using wavelength division multiple access (WDMA) in conjunction with an angle diversity receiver (ADR). Four wavelengths (red, yellow, green and blue) can be provided in this work based on the RYGB LDs transmitter used. Three room sizes are considered with two 8-user scenarios. A mixed-integer linear programming (MILP) model is proposed for the purpose of optimising the resource allocation. The optical channel bandwidth, SINR and data rate have been calculated for each user in both scenarios in all rooms. Room A, which is the largest room, can provide a higher channel bandwidth and SINR compared to the other rooms. However, all rooms can provide a data rate above 5 Gbps in both scenarios.
