Abstract :
We propose a novel adaptive frequency-domain equalization (FDE) scheme in digital coherent optical receivers, which can work with rationally-oversampled input sequences using the constant-modulus algorithm (CMA). Effectiveness of the proposed scheme is verified with 10-Gbaud dual-polarization QPSK transmission experiments.
