Performance Evaluation of Nonlinear IM/DD Optical OFDM with New SLM Scheme

The goal of this research was to describe a simple SLM technique for PAPR reduction in an optical OFDM system. FHT-based SLM approach with Riemann sequence as phase factor sequence is proposed for PAPR reduction in OOFDM-IM/DD system in this study effort. Optical orthogonal frequency-division multiplexing (O-OFDM) systems have attracted a lot of attention as a transmission technology for high-capacity long-haul optical transport networks. However, because to the high peak to average power ratio (PAPR) problem, it is just as susceptible to nonlinear effects as a traditional OFDM system. In the IM/DD Optical OFDM system, this study provides a Fast Hartley based selective mapping with Riemann Sequence for PAPR reduction. The proposed method outperforms other conventional methods in terms of PAPR and bit error rate performance, and it is also less difficult. In comparison to the standard technique, the proposed scheme minimises the peak to average power ratio of the OFDM signal and enhances the system’s BER performance. The usage of Riemann sequence and FHT based OOFDM reduces the complexity of the suggested method.
