AirFM-DDA: Air-Interface Foundation Model in the Delay-Doppler-Angle Domain for AI-Native 6G
Researchers introduce AirFM-DDA, a foundation model for 6G wireless networks that processes channel state information in the Delay-Doppler-Angle domain rather than traditional space-time-frequency representations. The model uses window-based attention instead of computationally expensive global attention, achieving superior generalization on channel prediction tasks while reducing computational costs by an order of magnitude.
