Fig. 4. EOE system frequency response of the white light, blue light, and yellow component in different cases (with or without PRE and POE).

Fig. 5. BER versus data transmission rate in different cases (white light, white light with PRE, white light with PRE and POE). A BER below 10−10 is truncated to this threshold. Inset: Eye diagram of the VLC system at different data rates (80, 150, 200, 250, and 300 Mbit/s). All of the measurements are taken at the distance of 1 m.

Fig. 6. Measured EVM versus data rate in different cases (without or with PRE and POE) based on the M-QAM scheme. All of the measurements are taken at the distance of 1 m.

Fig. 7. (a) Measured NRZ-OOK transmission data rate, received optical power, and illumination versus radial distance (1, 1.2, 1.4, 1.6, 1.8, 2.0, and 2.2 m). (b) Measured M-QAM (16, 32, and 64-QAM) data transmission rate, EVM and BER versus the radial distance (1, 1.4, 1.8, and 2.2 m).
