MIMO-GAN: Generative MIMO Channel Modeling [PDF]
ICC 2022 - IEEE International Conference on Communications, 2022 We propose generative channel modeling to learn statistical channel models from channel input-output measurements. Generative channel models can learn more complicated distributions and represent the field data more faithfully.
