Transmitter Diversity with Beam Steering [PDF]
2019 21st International Conference on Transparent Optical Networks (ICTON), 2019 Providing high data rates is one of the drivers in visible light communication (VLC) systems. This paper introduces a VLC system that employs transmitters diversity with beam steering to provide high data rates. In this work, red, yellow, green, and blue (RYGB) laser diodes (LD) are used as transmitters to obtain a high modulation bandwidth.
