“…In comparison with PAM-4 signals, PAM-8 signals can carry more information at the expense of more complicated digital signal processing (DSP), and probabilistic shaping (PS) and nonlinear equalizers were exploited to enhance the robustness of PAM-8 signals [9][10][11][12][13][14]. Furthermore, when the modulation amplitude is increased to PAM-16, the nonlinear equalization becomes more challenging for compensating the critical nonlinear impairments caused by the electro-optical components in the nonlinear operating region [15][16][17].…”
