Unbiased Channel Estimation Based on the Discrete Fresnel Transform for CO-OFDM Systems

In this letter, the deviation of the channel estimator based on intra-symbol frequency-domain averaging (ISFA) for coherent optical orthogonal frequency-division multiplexing (CO-OFDM) is investigated. The deviation-induced estimation error is derived analytically as a function of pulse broadening c...
