摘要: Visible light communication (VLC) using LEDs has attracted significant attention recently for the future secure, license-free and electromagnetic-interference (EMI)-free optical wireless communication. Dimming technique in LED lamp is advantageous energy efficiency. Color control can be performed red-green-blue (RGB) by dimming technique. It highly desirable to employ provide simultaneous color high speed VLC. Here, we proposed demonstrated a dimming-discrete-multi-tone (DMT) modulation. High DMT-based VLC with first time best of our knowledge. Demonstration analyses several modulation conditions transmission distances are performed, instance, demonstrating data rate 103.5 Mb/s (using RGB LED) fast Fourier transform (FFT) size 512.
