在本文中,我们解决了多用户 WDM 可见光通信 (VLC) 系统中波长资源分配的优化问题。采用混合整数线性规划 (MILP) 模型,可最大化所有用户的信号干扰加噪声比 (SINR) 之和。结果表明,优化多用户 WDM VLC 系统中的波长分配可以减少干扰的影响,并提高系统吞吐量(最多 7 个用户的数据速率总和)。
In this paper, we address the optimization of wavelength resource allocation in multi-user WDM Visible Light Communication (VLC) systems. A Mixed Integer Linear Programming (MILP) model that maximizes the sum of Signal-to-Interference-plus-Noise-Ratio (SINR) for all users is utilized. The results show that optimizing the wavelength allocation in multi-user WDM VLC systems can reduce the impact of the interference and improve the system throughput in terms of the sum of data rates for up to 7 users.
