Efficient Constant Modulus Based Carrier Frequency Offset Estimation for CO-OFDM Systems
This paper proposes a blind carrier frequency offset (CFO) estimation method for coherent optical orthogonal frequency division multiplexing (CO-OFDM) systems, using constant modulus signaling. The proposed scheme is based on a robust cost-function, which deviates from the common assumption that the...
