A novel probabilistic model for hybrid IM/DD AO-OFDM-CDMA which employs optical subcarrier hopping by means of the advanced 2D-HC signature
The optical link consists of an optical amplifier, an optical filter, and single mode fiber and loop control. Abstract—This letter proposes a design of low peak-to-average power ratio (PAPR), low symbol error rate (SER), and high data rate signal for optical orthogonal frequency division multiplexing (OFDM) systems. Various factors are elaborated within this context to ascertain a more effective O-OFDM approach, including constellation size, data arrangement and. 60 GHz millimeter-wave (mm-wave) frequency band is also becoming a most popular upcoming frequency. Orthogonal Frequency Division Multiplexing (OFDM) is a widespread technology in broadband communication (wired and wireless) because of its ability to cope with strong channel distortions (interference, frequency fading, multipath propagation). This paper investigates the architecture of single channel and four channel direct detection and coherent detection optical OFDM systems and carries out performance analysis based on bit error rate and Q-factor. In the case of single channels, a date rate of 10 Gbps is achieved while in 4 channel.
