“…According to different modulation and detection methods, optical OFDM systems can be divided into intensity modulation and direct detection (IM/DD), radio frequency up conversion and direct detection (RF/DD), radio frequency up conversion and coherent detection (RF/CO), and optical in-phase and quadrature modulation with CO detection (IQ/CO) [4]. Recently, IM/DD has been investigated for short-reach optical communication systems due to its low cost and operational complexity [5,6].…”

Intensity-modulation and direct-detection (IM/DD) orthogonal frequency division multiplexing (OFDM) systems have gained great attentions from researchers. However, the interaction between the chirp of direct modulation laser and fiber dispersion causes intermixing interferences among sub-carriers. Therefore, in this paper, we adopt Volterra filter to reduce the intermixing interferences and improve the BER performance in IM/DD OFDM systems. We first introduce the basic concept of Volterra filter and then set up simulation systems. The simulation results show that the system has a good BER performance by using a Volterra filter. This research provides a theoretical guidance for the information transmission in power grid.
