IM/DD-OFDM Modem Based on Adaptive Equalization

In this paper, the performance of different nonlinear electrical compensation techniques is evaluated. The goal is to enhance the transmission quality of intensity modulation (IM) and direct detection (DD) optical orthogonal frequency division multiplexing (OOFDM). The overall performance results are compared versus linear compensator equalizers. Also, studies here include the looking at the capability of Volterra based electrical equalizers for transmitted signal recovery.
