摘要：
A method decodes an optical signal transmitted over an optical channel from a transmitter to a receiver. The receiver receives the transmitted optical signal to produce a digital signal including data symbols and pilot symbols, and determines filtering coefficients based on an error between amplitudes of the received pilot symbols and amplitudes of transmitted pilot symbols, while ignoring errors between phases of the received pilot symbols and phases of the transmitted pilot symbols. The amplitudes and the phases of the transmitted pilot symbols are known at the transmitter and the receiver. The receiver filters the digital signal according to the filtering coefficients to produce a filtered signal with equalized amplitude and an unconstrained phase demodulates and decodes the filtered signal to produce an estimate of the transmitted optical signal.
