A real-time 106 Mbit/S visible light communication system design using general lighting LED with analog pre-emphasis

This paper presents a real-time 106 Mbit/s visible light communication (VLC) system using only non-return-to-zero on-off keying (OOK-NRZ) modulation and general lighting LED. With a pre-emphasis module based LED driver, the 3-dB modulation bandwidth of VLC link is extended from 4 to 106 MHz. Given the BER upper Limit was 1.3 × 10−3, the highest bit rates achieved through the designed system were 106 and 98 Mbit/s at the distances of 60 and 70 cm, respectively
