This letter reports an experimental demonstration of high-speed indoor optical wireless Optical multiple-input multiple-output (MIMO)-orthogonal frequency division multiplexing (OFDM) system with an imaging receiver. The system consists of a 2×1 array of white LEDs that transmit data to a 9 channel imaging receiver that uses a 3×3(More)
This paper presents an experimental comparison of optical orthogonal frequency division multiplexing (OFDM) approaches in visible light communications (VLC). We demonstrate that OFDM schemes with asymmetric signals suffer from baseline wander in practical transmission experiments, which degrades the overall bit-rate performance. Several schemes that combat(More)
