Adaptive Control of OFDM Data Rate for LED Visible Light Communications in Different Free Space Transmission Distances and Offsets

Not Accessible

Your library or personal account may give you access

Abstract

Using orthogonal-frequency-division-multiplexing (OFDM) for light-emitting-diode (LED) visible-light-communication (VLC) is a promising approach. Here we demonstrate an LED communication link with adaptive control of the OFDM data rate for different communication environments.
