Alamouti Coded Asymmetrically Clipped Optical OFDM for Improved Performance of Multi-Mode Fiber

In this work, Alamouti coded asymmetrically clipped optical orthogonal frequency division multiplexing technique is investigated in a multimode fiber (MMF) transmission. Analysis is carried out on asymmetrically clipped O-OFDM and MMF models. The proposed technique finds significant improvement of bit error rate and received signal to noise ratio compared to conventional optical OFDM technique in MMF transmission.
