Summary:
Visible light communication (VLC) has attracted much attention with the growth of a light emitting diode (LED). An LED has ability to blink at high speed compared to a fluorescent lamp. Therefore, we consider a multiple-input single-output (MISO) VLC system using multiple LEDs. However, signal distortion caused by a limited frequency response of LED drive circuits leads a bottleneck in transmission rate improvement. Hence in this paper, we propose a novel demodulation method based on the Viterbi algorithm. The proposed method has high performance in robustness against signal distortion, and provides 80% improvement in a transmission rate compared to the conventional method.
