Improving bit error rate in optical wireless OFDM systems through hybrid companding and precoding strategies

EURASIP Journal on Wireless Communications and Networking
Visible light communication (VLC) is a promising wireless high-data-rate transmission technology that uses visible light. Optical Orthogonal Frequency Division Multiplexing (OOFDM)-based systems, especially asymmetrically clipped optical OFDM (ACO-OFDM),
