Abstract
In this letter, the modulation and demodulation mechanisms of the discrete Fourier transform-based optical fast orthogonal frequency-division multiplexing (F-OFDM) scheme have been examined. Analysis shows that there exists an interference term between even and odd subcarriers in this F-OFDM scheme, which has severe impact on system performance, especially when the subcarrier number is small. We propose a zero-subcarrier-based method and numerically investigate the effectiveness of the method with different number of subcarriers. Simulation results show that the approach can greatly mitigate the interference in DFT-based F-OFDM scheme.
