Abstract :
The effects of different system parameters on the performance of real-time optical orthogonal frequency-division-multiplexing (OFDM) transceivers are investigated. Numerical simulations are carried out to search for the optimum arithmetic precision of the fast Fourier transform and its inverse (FFT/IFFT) which are key components in optical OFDM transceivers.
