We experimentally demonstrate a tunable and reconfigurable optical DFT to demodulate 10-40-Gbuad OFDM with 2/3/4 subcarriers at 20/40GHz frequency spacing. Average power penalty of ~7 dB at BER of 10 ...
We consider application of the discrete Fourier transform-spread orthogonal frequency-division multiplexing (DFT-spread OFDM) technique to high-speed fiber optic communications. The DFT-spread OFDM is...
