Title
A spatial dimming scheme based on transmit antenna selection for multiuser MISO VLC systems
Abstract
The multi-user multiple-input single-output (MU-MISO) visible light communications (VLC) system, which can serve multi-users simultaneously, have been widely studied in recent years. Dimming control is one of the main topics in VLC systems. In this paper, we proposed a novel transmit antenna selection based spatial dimming (TAS-SD) scheme for zero forcing (ZF) precoded MU-MISO VLC systems. By taking full advantage of the channel state information at both the transmitter and the users, the proposed TAS-SD scheme can combine the precoding and transmit antenna selection (TAS) technique together, and effectively improves the performance of dimmable MU-MISO systems. Simulation results show that the proposed TAS-SD scheme has significant bit error-ratio performance gains over the conventional analog dimming (AD) scheme at various dimming proportions and user positions. These advantages make it a promising candidate dimming scheme for ZF precoded MU-MISO VLC systems.
