no code implementations3 Nov 2022 Emre Ozfatura, Yulin Shao, Amin Ghazanfari, Alberto Perotti, Branislav Popovic, Deniz Gunduz

Deep neural network (DNN)-assisted channel coding designs, such as low-complexity neural decoders for existing codes, or end-to-end neural-network-based auto-encoder designs are gaining interest recently due to their improved performance and flexibility; particularly for communication scenarios in which high-performing structured code designs do not exist.

Learning to Perform Downlink Channel Estimation in Massive MIMO Systems

no code implementations6 Sep 2021 Amin Ghazanfari, Trinh Van Chien, Emil Björnson, Erik G. Larsson

The second one is a deep-learning-based approach that uses a neural network to identify a mapping between the available information and the effective channel gain.
