LED-based Visible Light Communication in a Practical Indoor Interfered Environment Employing DMT and STBC

Abstract

We demonstrate practical indoor VLC of 3.2-m transmission, and investigate multipath interference between LEDs. Employing repetition coding, 161 similar to 266-Mbps DMT-signals are achieved depending on interference severity. Employing STBC, about fixed 220-Mbps data rate could be achieved.
