Carrier Frequency Offset Estimation for CO-OFDM: The Matched Filter Approach
₹4,500Carrier Frequency Offset Estimation for CO-OFDM: The Matched Filter Approach Abstract-This paper proposes a novel carrier frequency offset (CFO) estimator for coherent optical orthogonal frequency division multiplexing (CO-OFDM) systems using the matched filter (MF) concept. We consider an OFDM symbol with N subcarriers so that the receiver takes N time-samples of the received noisy CO-OFDM…
