Title
Massive MIMO For Indoor VLC Systems
Abstract
Visible light communication (VLC) systems are typically operating at low data rates (hundreds of Mb/s up to 1 Gb/s). Operation at higher data rates can be feasible for VLC systems by implementing massive multiple-input and multiple-output (MIMO) techniques. The proposed VLC systems consists of multiple luminaires powered by light emitting diodes (LEDs) which are acting as transmitters and optical imaging receiver that includes massive number of separated multiple photodetectors. The massive MIMO-VLC system employs a space division multiple access (SDMA) to support multi-users in addition to the increase the data rate of a single user and improve the received signal to noise ratio (SNR) through use the spatial multiplying (SM), maximal ratio combining (MRC) and transmit/receive diversity (TxD, RxD) techniques, respectively. The result show that our massive MIMO-VLC systems able to work at a high data rate of 4 Gb/s for a single user scenario while considering the effect of mobility and diffuse reflections. In addition, the results show that our proposed system able to work at a high data rate of 1.5 Gb/s for multi-user scenario in presence of the multi-user interfere (MUI).
