Abstract
•We propose a phase noise averager for binary PSK signals.•The system is an opto-electrical feed-forward circuit.•Simulations show its noise reduction effect.•Several issues suggested by the reviewers are discussed.
This paper proposes an opto-electrical feed-forward circuit that reduces phase noise in binary PSK signals by averaging the noise. Random and independent phase noise is averaged over several bit slots by externally modulating a phase-fluctuating PSK signal with feed-forward signal obtained from signal processing of the outputs of delay interferometers. The simulation results demonstrate a reduction in the phase noise.
