Transformer-Based Neural Surrogate for Link-Level Path Loss Prediction from Variable-Sized Maps

no code implementations6 Oct 2023 Thomas M. Hehn, Tribhuvanesh Orekondy, Ori Shental, Arash Behboodi, Juan Bucheli, Akash Doshi, June Namgoong, Taesang Yoo, Ashwin Sampath, Joseph B. Soriaga

The transformer model attends to the regions that are relevant for path loss prediction and, therefore, scales efficiently to maps of different size.

Over-the-Air Design of GAN Training for mmWave MIMO Channel Estimation

1 code implementation25 May 2022 Akash Doshi, Manan Gupta, Jeffrey G. Andrews

More importantly, our proposed framework has the potential to be trained online using real noisy pilot measurements, is not restricted to a specific channel model and can even be utilized for a federated OTA design of a dataset generator from noisy data.
