Breaking the CP Limit: Robust Long-Range OFDM Sensing via Interference Cleaning
Umut Utku Erdem, Lucas Giroto, Benedikt Geiger +6
In orthogonal frequency-division multiplexing-based radar and integrated sensing and communication systems, the sensing range is traditionally limited by the round-trip time corres…
