We developed a flicker-free and high-speed visible light communication (VLC) system by using optimally modulated signals emitted from illumination devices. The proposed system achieved 75 kbps at maximum through experiments using a commercially-available camera (60 fps, 1080 line sensors), which goes beyond the theoretical upper limit of existing VLC systems implementing the on-off keying modulation. We clarified the performance of VLC systems using OFDM modulated multicarrier signals through theoretical analyses. Based on them, we devised a system for\u00a0selective communication\u00a0between multiple cameras whose exposure time ratios are mutually different.<\/p>\n<\/div>\n\n\n\n
