Physics-guided residual Kolmogorov-Arnold network equalizer for high-speed dual-polarization coherent optical transmission.
We propose a physics-guided residual Kolmogorov-Arnold network (RN-KAN) equalizer for nonlinear impairment compensation in high-speed dual-polarization (DP) 16-QAM coherent transmission. RN-KAN combines a multiple-input multiple-output finite-impulse-response (MIMO-FIR) backbone with spline-gated residual branches cons...
