DRIFT: Joint Channel Estimation and Prediction Towards Pilotless 6G Non-Terrestrial Networks
Researchers propose DRIFT, a lightweight AI framework for channel estimation and prediction in 6G non-terrestrial networks that reduces pilot overhead by up to 12% while requiring minimal computational resources suitable for satellite implementation. The approach uses data-driven processing after initial pilots, achieving significant spectral efficiency gains with fewer than 200k multiply-accumulate operations.
