我们提出了一种使用角度分集检测器的成像接收器（ImR），用于基于室内空分复用的可见光通信（SDM-VLC）系统。与使用垂直定向探测器的传统 ImR 相比，所提出的成像角度分集接收器（ImADR）具有两个主要优点，包括更宽的视场（FOV）和更高的光学增益。通过理论分析和蒙特卡罗模拟来评估所提出的 ImADR 在室内四通道 SDM-VLC 系统中的性能。分析结果表明，对于10(-3)的目标误码率，所提出的基于ImADR的SDM-VLC系统比使用传统ImR的系统实现了44%的发射光功率降低和130%的覆盖范围改善。
We propose an imaging receiver (ImR) using angle diversity detectors for indoor space division multiplexing-based visible light communication (SDM-VLC) systems. Compared with a conventional ImR which utilizes vertically oriented detectors, the proposed imaging angle diversity receiver (ImADR) enjoys two main advantages, including a wider field-of-view (FOV) and higher optical gain. Both theoretical analysis and Monte Carlo simulations are carried out to evaluate the performance of the proposed ImADR in an indoor four-channel SDM-VLC system. Analytical results show that, for a target bit error rate of 10(-3), the proposed ImADR-based SDM-VLC system achieves 44% reduction in the transmit optical power and 130% coverage improvement than the system using a conventional ImR.
