Annotation. Indoor Visible Light Communication (VLC) methods are expected to use LED
infrastructure to provide data transmission and general lighting. To fully cover the area of
illumination, several LEDs must be used. Each bulb is made up of an array of LEDs. In a typical VLC
channel simulation, each array is usually treated as a single point source. This simplification provides
very low computational complexity, but may lead to inaccurate modeling in some cases. This article
compares various LED array approximation schemes in terms of channel characteristics. The exact
structure of each array or approximate constellation is considered.
