Abstract

An ideal Visible Light Communication (VLC) system should facilitate reliable data transmission at high throughputs, while also providing flicker-free illumination at the user-defined dimming level. In this spirit, we conceive a unary code aided dimming scheme for On-Off Keying (OOK) modulated VLC systems. The proposed unary-coded scheme facilitates joint dimming and throughput control, while relying on iterative decoding. It is demonstrated that the proposed unary-coded dimming scheme provides attractive throughput gains over its contemporaries and it is also capable of approaching the theoretical throughput limit. Furthermore, we design novel joint dimming-Forward Error Correction (FEC) coding schemes, which significantly outperform their compensation time dimming based counterparts in terms of the attainable Bit Error Rate (BER) performance as well as the throughput. Finally, in the quest for approaching the capacity, we also optimize our system using EXtrinsic Information Transfer (EXIT) charts and demonstrate an SNR-gain of up to 6 dB over the compensation time dimming based classic benchmarker.
