论文摘要
丰富的光谱是6G通信系统电磁光谱的有前途的部分。可见光光谱是光谱的一部分，可用于同时提供通信和照明。可见光通信（VLC）系统已经广泛研究，但是，很少的工作集中在多次访问领域。本章研究VLC系统中的波长部门多访问（WDMA）技术，以支持多个用户。此外，在本章中，通过开发一个混合构成线性编程（MILP）模型来考虑资源分配的优化，该模型可用于在支持多个用户的同时最大化信号与噪声和干扰比（SINR）。优化的资源分配导致访问点（AP）和波长的最佳分配给用户。本章评估了不同的室内环境，例如办公室，数据中心和飞机舱。具有四个波长（红色，绿色，黄色和蓝色）的激光二极管（LD）用于提供高带宽以进行通信和白光以进行照明。同样，通过利用空间域来减少角度多样性接收器（ADR）接收信号并减少噪声和干扰。
The abundant optical spectrum is a promising part of the electromagnetic spectrum for 6G communication systems. The visible light spectrum which is a part of the optical spectrum, can be used to provide communication and illumination simultaneously. Visible light communication (VLC) systems have been widely researched, however, little work has focused on the area of multiple access. This chapter studies wavelength division multiple access (WDMA) techniques in VLC systems to support multiple users. In addition, the optimization of resource allocation is considered in this chapter by developing a mixed-integer linear programming (MILP) model that can be used to maximize the signal to noise and interference ratio (SINR) while supporting multiple users. The optimized resource allocation results in the best assignment of access points (APs) and wavelengths to users. Different indoor environments such as office, data center and aircraft cabins are evaluated in this chapter. A laser diode (LD) with four wavelengths (red, green, yellow and blue) is used to provide high bandwidth for communication and white light for illumination. Also, an angle diversity receiver (ADR) is utilized to receive signals and reduce noise and interference by exploiting the spatial domain.
