KO codes: Inventing Nonlinear Encoding and Decoding for Reliable Wireless Communication via Deep-learning [article]

Ashok Vardhan Makkuva, Xiyang Liu, Mohammad Vahid Jamali, Hessam Mahdavifar, Sewoong Oh, Pramod Viswanath
2021 arXiv   pre-print
In this paper, we construct KO codes, a computationaly efficient family of deep-learning driven (encoder, decoder) pairs that outperform the state-of-the-art reliability performance on the standardized  ...  Landmark codes underpin reliable physical layer communication, e.g., Reed-Muller, BCH, Convolution, Turbo, LDPC and Polar codes: each is a linear code and represents a mathematical breakthrough.  ...  Acknowledgements Ashok would like to thank his colleagues Mona Zehni and Konik Kothari for helpful discussions about the project.  ...
