NGMI and Kullback–Leibler Divergence in High-Baudrate PAM Transmission with Severe Bandwidth Limitation
We demonstrate 93-Gbaud PAM transmission with or without nonlinear differential coding in O-band experiment with 10-dB bandwidth of 32 GHz, in which the coding scheme realizes the lower Kullback-Leibler divergence and the higher NGMI.
