A Half Bit Interleaved RZ-OOK Modulation for LED Based Visible Light Communication

Abstract

Efficient data transmission with LED is a topic of increasing interest in visible light communication. In this work, we proposed a half bit interleaved RZ-OOK modulation scheme. Compared to traditional RZ-OOK modulation, the data rate can be doubled by the proposed scheme. The experiment demonstrated that, with commercial LED (LED465E), the bit rate can achieve 160Mbit/s with the measured BER below the FEC limit of 3.8x10-3.
