Hello
I understand that you need an expert in MatLab with Electrical Engineering background (VLC).
I am a +5 years researcher in electrical engineering field specifically in VLC, wireless communications, and quantum communications. Please visit my Google Scholar regarding my publications:

Your project description is not clear to me. As you know, we can only use line of sight transmission in VLC. Thus, sending msg from one room to another one with VLC is not possible. However, I can implement OFDM (ACO and DCO) in VLC in general.
I would be glad if I can help you with your project. Please feel free to contact me for further information.
Looking forward to hear from you,
Best regards,
