DOI: 10.1007/s11082-021-02736-y
Abstract: This paper presents a modification in conventional asymmetrically clipped optical OFDM (ACO-OFDM) frame for direct detection intensity modulation (DD-IM) system. The conventional ACO-OFDM for DD-IM utilizes only one-fourth of available subcarriers for information symbols and… read more here.
