Abstract

In this paper, we have experimentally demonstrated faster-than-Nyquist carrierless amplitude and phase modulation quadrature phase-shift keying visible light communication system over 1.5-m free space transmission. Weighted look-up table is used to mitigate nonlinear impairment caused by amplifiers and electro-optical components. At the receiver side, recursive least square is employed to improve the decision precision. By combining these techniques, a data rate of 1.01 Gb/s is experimentally achieved with a bit error rate less than 7% forward error correction limit of 3.8 x 10<superscript>-3</superscript>. To the best of our knowledge, this is the first time that weighted look-up table is proposed and used in visible light communication system. [ABSTRACT FROM AUTHOR]
