I am interested in simulation and numerical methods for VLC systems. The method which considers light propagation, reflection, refraction, ... .
I am new to this area and I don't know exactly what methods are available and what the capabilities are. The only method I heard about is ray-tracing.
Could you please give me some primitive idea about existing simulation methods and if possible introduce some reference and source to read. Thank you in advance.
I hope these papers to help you.
You can also find more literature in their references.
Best Luck.

Hi,
To start simulation in FSO,YOU CAN USE OPTICAL SIMULATION SOFTWARES LIKE Optisystem and VPI Photonics. If they are not available you can use matlab.
I suggest you to go through the channel modelling by Gamma-Gamma distribution and maths related to LED emission(lambertian). Gamma-Gamma distribution is widely used.
You can use simulink to design the channel in matlab and then analyze VLC system using LED/laser transmitter.
You can start with this book

Also you can contact openVLC.org for hardware and linux based physical and mac layer implementation.

Hello,
I also suggest starting with the book which Muhammad Tabish Niaz recommends to have a background. Then, I recommend to use the advanced ray tracing approach based on OpticStudio software due to the following advantages:
1. It allows considering either the symmetric or asymmetric radiation pattern of light sources.
2. It allows considering either LOS or NLOS components where a large number of reflections can be analyzed.
3. It allows us to consider the wavelength-dependent reflectance of materials as well as the type of reflection.
4. It allows also considering the effect of diverse atmospheric weather conditions.
This approach has been recently validated by the measurements in different indoor scenarios including LOS and NLOS cases. Please have a look at our latest paper. Let me know if you have any questions regarding to it.

Optical simulation software such as Optisystem and VPI Photonics may be used to initiate simulations in Free Space Optics (FSO). However, it is essential to note that these software options are not free of charge.
The utilizatiUsingon of MATLAB is possible to investigate the VLC system via the employment of Simulink. This requires the design of a channel inside MATLAB and analyzing the system using an LED or laser transmitter.
