Rabby3223/Optical-camera-communication-with-four-level-flicker-mitigation ? reverse-engineered prompt

Build me a MATLAB project for optical camera communication with four level flicker mitigation.

I want one part that generates the transmitted PAM4 light signal with the proposed flicker mitigation method, and another part that reads the captured data, decodes it, reconstructs the packet, and estimates BER. Please make it work with the sample data that comes with the repo, including the base64 encoded CSV capture files and the provided sequence and reference data.

It should be easy to run from the transmitter side or receiver side with a few clear settings like symbol rate, block length, and which mitigation method to use, either the proposed scheme or the Manchester like version. If anything is missing, please use the included files and look up current MATLAB docs online if you need to. I’d also like the code to be organized so I can understand the flow from signal generation to decoding without having to dig through too much.
