An aggregate data rate of 6.36 Gbit/s of RGB 2X2 MIMO VLC system is demonstrated for the proof-of-concept. Moreover, the corresponding VLC rates under the free-space transmissions of 1 to 3 m are also analyzed.

We experimentally demonstrated a 2x2 multiple-input multiple-output (MIMO) visible light communication (VLC) system using commercial phosphorescent white light emitting diodes (LEDs) and low-cost PIN photodiodes (PDs). Additionally, a pre-equalizer was used to extend the available modulation bandwidth up to 100 MHz. Using spectral-efficient orthogonal frequency division multiplexing (OFDM) modulation with bit-loading algorithm, we successfully achieved high-speed VLC transmission at > 1 Gbit/s over a free-space link of 0.6 m.
