Abstract: In this letter, we aim for maximizing the throughput of a VLC system. Explicitly, we conceive a Soft-In Soft-Out (SISO) decoder providing soft feedback for the classic Run Length Limited (RLL) codes, hence facilitating iterative decoding for exchanging valuable extrinsic information between the RLL and the error correction modules of a VLC system. Furthermore, we propose a Unity Rate Code (URC) for our VLC system, which hence becomes capable of matching the On-Off Keying (OOK) capacity, while maintaining a flicker-free dimming value of 50%.
