Currently, I am quite interested in error correction for VLC system and I am trying to think of some possible similarities in error correction scenario between the usual RF wireless communication system and VLC system.
In RF system, sometimes burst error and random error could happen so I guess the same phenomenon might occur in VLC system.
The only reasonable I could come up with is that sometimes people put their hands or body parts which obscure the light and cause disruption of the data stream ?
Further more, I really hope to receive some sample code for the MATLAB simulation of burst error in vlc.
Thank you very much
Adding to Albert Manfredi burst error is cause by burst noise or an interruption of the radiation incident to the detector. Burst noise can be generated by the detector or can be an interference from nearby light sources. The noise has pronounced effect when the light is weak.

What about any sudden increase in ambient light? Something drastic possibly, like someone using a flash to take a picture. But also something less drastic, like turning on more lights in the room, or opening a shade to let in sunlight, before the receiver has a change to adjust (assuming it can adjust). Obstructions would also cause errors, as you pointed out already.

Thank you very much.
Mr Alfredi and Mr Abdelahim are there any existing study and simulation code on the phenomena that you have described: flash camera, opening a shade, inteference from nearby source.
It would be great if there is some existing paper on this issue
This is something really interesting and practical
