Coherent Optical OFDM With Index Modulation for Long-Haul Transmission in Optical Communication Systems
In this paper, it is proposed to enhance coherent optical orthogonal frequency-division multiplexing (OFDM) system by using index modulation in terms of bit error rate (BER) and spectral efficiency for different levels of the fiber nonlinearity. In the coherent optical OFDM with index modulation sys...
