Abstract
This paper presents an improved scheme to enhance the bit error rate (BER) for indoor visible light communication (VLC) systems. The proposed scheme uses cascaded codes-based channel code and least square discrete Fourier transform (LS-DFT)-based channel estimation to improve the robustness of the indoor optical wireless communication link. The simulation results demonstrate that a 3–5 dB signal noise rate (SNR) gain can be achieved when the BER is 10−3 below the forward error correction (FEC) limit for a 16-quadrature amplitude modulation (QAM) asymmetrically clipped optical orthogonal frequency-division multiplexing (ACO-OFDM) visible light communication system.
