Abstract :
We propose an efficient dispersion compensation to reduce the guard interval in coherent optical-orthogonal frequency division multiplexing (CO-OFDM) systems. The proposed algorithm compensates dispersion using overlapped frequency domain equalizer (OFDE), timing offset at the transmitter. Simulations verify the validity of the proposed algorithm.
