FPGA Implementation of Multi-Layer Machine Learning Equalizer with On-Chip Training

Keren Liu, Erik Börjeson, Christian Häger +1

We design and implement an adaptive machine learning equalizer that alternates multiple linear and nonlinear computational layers on an FPGA. On-chip training via gradient backprop…

Over-the-fiber Digital Predistortion Using Reinforcement Learning

Jinxiang Song, Zonglong He, Christian Häger +4

We demonstrate, for the first time, experimental over-the-fiber training of transmitter neural networks (NNs) using reinforcement learning. Optical back-to-back training of a novel…

Autoencoder-Based Unequal Error Protection Codes

Vukan Ninkovic, Dejan Vukobratovic, Christian Häger +2

We present a novel autoencoder-based approach for designing codes that provide unequal error protection (UEP) capabilities. The proposed design is based on a generalization of an a…

End-to-end Autoencoder for Superchannel Transceivers with Hardware Impairment

Jinxiang Song, Christian Häger, Jochen Schröder +2

We propose an end-to-end learning-based approach for superchannel systems impaired by non-ideal hardware component. Our system achieves up to 60% SER reduction and up to 50% guard…

Pruning and Quantizing Neural Belief Propagation Decoders

Andreas Buchberger, Christian Häger, Henry D. Pfister +2

We consider near maximum-likelihood (ML) decoding of short linear block codes. In particular, we propose a novel decoding approach based on neural belief propagation (NBP) decoding…
