摘要：
Multiple input/multiple output (MIMO) is a viable technique used to overcome the drawbacks of limited bandwidth and to improve the achievable rate of white light-emitting diodes (LEDs) in a visible light communication (VLC) system, where the LEDs are used to simultaneously deliver illumination and data communication. The indoor VLC system performance depends on the achievable rate distribution on the receiver side. In this study, we investigated the effect of the spatial distance between four photodiodes (PDs), the spatial distance between four LEDs (4 × 4 MIMO-VLC system), and the impact of the LED half-power angle on the data rate for an indoor VLC system. Different MIMO techniques such as spatial diversity (SD), spatial multiplexing (SMP), SD/SMP switching, adaptive SMP (aSMP), and SD-aided aSMP (SD-aSMP) were exploited. The results showed that if the distance between the PDs is increased, then the achievable data rate throughout the room is enhanced. However, if the distance between the LEDs is increased, then the achievable data rate is reduced. Moreover, if the LEDs half-power angle is well optimized it gives better results. From the simulation results, gains of 1.4 and 5 bit/s/Hz were obtained using SD and SMP, respectively. Therefore, the achievable data rate highly depends on the transceiver parameters. © 2021 Begell House Inc.. All rights reserved.
