1-Gb/s Transmission Over a Phosphorescent White LED by Using Rate-Adaptive Discrete Multitone Modulation
TL;DR: A VLC system based on a white LED for indoor broadband wireless access has been demonstrated, with twice the highest capacity that had been previously obtained by using an optimized discrete multitone modulation technique and adaptive bit- and power-loading algorithms.
Journal ArticleDOI
3.4 Gbit/s visible optical wireless transmission based on RGB LED
TL;DR: A gigabit-class indoor visible light communication system using commercially available RGB White LED and exploiting an optimized DMT modulation is experimentally realized and the resulting bit error ratios are the highest ever achieved in VLC systems.
Proceedings ArticleDOI
Experimental demonstration of high speed underwater visible light communications
Giulio Cossu,Raffaele Corsini,A. M. Khalid,S. Balestrino,A. Coppelli,Andrea Caiti,Ernesto Ciaramella +6 more
TL;DR: High-speed underwater optical wireless transmission over 2.5 m distance is experimentally proved, using different bit rates and modulation schemes, and in all the experimental conditions the authors achieve error free transmission.
Journal ArticleDOI
Mitigating LED Nonlinearity to Enhance Visible Light Communications
Xiong Deng,Shokoufeh Mardanikorani,Yan Wu,Kumar Arulandu,Bin Chen,A. M. Khalid,Jean-Paul M. G. Linnartz +6 more
TL;DR: It is shown that recombination rates of photon generation can be translated into an equivalent discrete-time circuit that can be inverted, allowing a new pre-distorter with a simpler and more efficient structure than previously studied and overly generic approaches to be developed.
Proceedings ArticleDOI
A Visible Light localization aided Optical Wireless system
TL;DR: It is shown experimentally that by combining the LoS OWC system with the localization algorithm it is possible to provide a gross data-rate exceeding 300 Mb/s over a 90° illumination angle by using a RGB visible-light LED at 90cm distance.
