Boundaryless Visible Light Communication System Without Attocell for Industrial Internet of Things

Investigation of rotating cubic receiver for mobile users in visible light communication systems

“…Reference [6][7]separates the received signal light from different directions by designing the receiver structure, which effectively reduces the interference. [8] proposed a boundaryless none-attocell VLC system and every transmitter transmits signals using all available communication resources, but it only considers the situation of receiver translation, which limits the application scenarios to a certain extent.…”

“…According to the above research, to further meet the mobile characteristics of industrial manufacturing terminals, reduce signal interference in overlapping areas and improve communication performance, we optimized the channel identification method for the scenario of receiver rotation based on the [8]. We also formulated an optimization problem to find out optimal rotation angle of the cubic receiver so as to realize the single-channel and multi-channel signal reception in the overlapping and non-overlapping areas.…”
