Multi-Dimensional Pulse-Shaping FIR Filter for Nonlinear Interference Alignment


Abstract:

We design an irregular pulse-shaping filter to mitigate nonlinear distortion in optical fiber transmission. Our optimized four-dimensional filter allowing nonphysical rotations achieves up to 0.55 dB gain over standard root-raised-cosine (RRC) Nyquist shaping.
