Paper Abstract

We perform a thorough performance and complexity analysis of a recently proposed Volterra series nonlinear equalizer (VSNE) for digital post-compensation of nonlinear fiber impairments in high-speed and long-haul coherent optical communication systems. Using a maximum absolute value selection criteria, we implement a pruning strategy for the matrix-based VSNE and compare its performance/complexity with the symmetric VSNE (symVSNE) and simpli ed VSNE (simVSNE) algorithms. The theoretical analysis is supported by simulation results obtained for a single-channel 224 Gb/s PM-16QAM transmission system with a signal propagation distance of 1920 km.
