Subcarrier Power Loading for Coherent Optical OFDM Optimized by Machine Learning
Enhanced power loading based on machine learned subcarrier interactions and nonlinear SNR progression is proposed to improve BER performance in optical coherent OFDM systems, achieving a gain of 0.5 dB in OSNR vs. classical schemes.
