Abstract :
We propose and numerically evaluate a simplified pre-distortion algorithm to compensate intra-channel nonlinearity for 16QAM, which provides gate-count reduction through multiplier-free implementation. We confirm the tolerance to chromatic dispersion uncertainty and the applicability to different pulse formats.
