This paper presents a real‐time OFDM‐based visible light communication (VLC) system utilizing a single InGaN/GaN multiquantum‐wells (MQWs) light emitting diode (LED). An MQWs LED with 3 dB electrical bandwidth of 23.8 MHz is developed as the transmitting device. Orthogonal frequency division multiplexing (OFDM) is employed to ensure the LED bandwidth is fully used, and the system is designed and implemented on a field‐programmable gate array platform to realize real‐time communication. The real‐time OFDM‐VLC system achieves a rate of 96 Mbit/s at the distance of 2 m, and the bit error ratio (BER) is 2.25 × 10−3, which is below the forward error correction (FEC) limit.
