I think the book entitled " Optical Wireless Communications: System and Channel Modelling with MATLAB " contents different codes for visible light communication
Thanks for you input. This book has some sort of experiment . But I am specfic about NOLS containing an Object based matlab code. . Hope you understand my point.
Muhammad Irshad Regarding visible light communication LOS/NOLS containing an Object, you can search websites or open profiles of co-authors of the reference paper you are investigating. Github is also a good resource for you.
