论文摘要
光学无线通信（OWC）系统已成为引起极大兴趣的主题，因为它们可以在第六代（6G）无线通信中使用，以同时提供高数据速率并支持多个用户。本文使用波长分区多访问（WDMA）方案研究了接收器方向对光学无线系统中资源分配的影响。在这项工作中检查了三个具有不同接收器方向的不同系统。这些系统中的每一个都在两种情况下考虑8个同时用户。 WDMA用于支持多个用户，并基于每个AP的红色，黄色，绿色和蓝色（RYGB）LDS提供的四个波长。每个系统中使用角度多样性接收器（ADR）。通过使用混合智能线性编程（MILP）模型获得了从波长和接入点（AP）方面的优化资源分配。在所有系统中的两种情况下，确定了通道带宽和SINR。结果表明，接收器方向的变化会影响通道带宽和SINR的水平。但是，在所有用户的两种情况下，sinrs都高于阈值（15.6 dB）。在所有系统中，在两种情况下，获得的SINR都可以支持5.7 Gbps的T数据速率。
Optical wireless communication (OWC) systems have been the subject of a significant amount of interest as they can be used in sixth generation (6G) wireless communication to provide high data rates and support multiple users simultaneously. This paper investigates the impact of receiver orientation on resource allocation in optical wireless systems, using a wavelength division multiple access (WDMA) scheme. Three different systems that have different receiver orientations are examined in this work. Each of these systems considers 8 simultaneous users in two scenarios. WDMA is utilised to support multiple users and is based on four wavelengths offered by Red, Yellow, Green and Blue (RYGB) LDs for each AP. An angle diversity receiver (ADR) is used in each system with different orientations. The optimised resource allocations in terms of wavelengths and access point (AP) is obtained by using a mixed-integer linear programming (MILP) model. The channel bandwidth and SINR are determined in the two scenarios in all systems. The results show that a change in the orientation of the receiver can affect the level of channel bandwidth and SINR. However, SINRs in both scenarios for all users are above the threshold (15.6 dB). The SINR obtained can support t data rate of 5.7 Gbps in both scenarios in all systems.
