Reservoir Computing-based Multi-Symbol Equalization for PAM 4 Short-reach TransmissionYevhenii Osadchuk, Ognjen Jovanovic, Darko Zibar et al.
We propose spectrum-sliced reservoir computer-based (RC) multi-symbol equalization for 32-GBd PAM4 transmission. RC with 17 symbols at the output achieves an order of magnitude reduction in multiplications/symbol versus single output case while maintaining simple training.

Experimental Evaluation of Computational Complexity for Different Neural Network Equalizers in Optical CommunicationsPedro J. Freire, Yevhenii Osadchuk, Antonio Napoli et al.
Addressing the neural network-based optical channel equalizers, we quantify the trade-off between their performance and complexity by carrying out the comparative analysis of several neural network architectures, presenting the results for TWC and SSMF set-ups.
