Abstract :
We propose a coherent optical OFDM system using modified DFT windows to improve dispersion tolerance for ultra-long-haul transmission systems. Simulation results show that the proposed system can greatly enhance the dispersion tolerance compared with the conventional coherent optical OFDM system.
