Advanced Equalization in 112 Gb/s Upstream PON Using a Novel Fourier Convolution-based Network

arXiv:2405.02609v1 Announce Type: new
Abstract: We experimentally demonstrate a novel, low-complexity Fourier Convolution-based Network (FConvNet) based equalizer for 112 Gb/s upstream PAM4-PON. At a BER of 0.005, FConvNet enhances the receiver sensitivity by 2 and 1 dB compared to a 51-tap Sato equalizer and benchmark machine learning algorithms respectively.
