Calibrating the Channel Twin: Sim-to-Lab Adaptation at W-Band
Build a site-specific Sionna RT channel twin → Capture real OFDM CFRs on a COTS W-band testbed (USRP-B200 + WR-10 converters, 92–95 GHz) → Learn an unpaired, non-adversarial mapping that aligns the channel statistics receivers actually care about: PDP, sub-band PDP, RMS delay-spread distribution, and per-subcarrier magnitude
No paired simulated/measured samples. No discriminators. No retraining per carrier — the 95 GHz checkpoint transfers zero-shot to 92–94 GHz!!
Digital Twin Empowered DRL for UAV Aerial Corridors
You want real-time, interference-aware UAV-BS-beam association — without global CSI overhead and without NP-hard combinatorial search at every decision step? Try this approach!!
