LWM-TF: A Wireless Foundation Model on 5G NR Time-Frequency Resource Grids
Namhyun Kim, Sadjad Alikhani, Ahmed Alkhateeb
Received OFDM grids preserve both pilot and payload observations, yet wireless foundation models are rarely pre-trained on them. We introduce LWM-TF, a 9.58M-parameter factorized m…

LWM-Spectro: A Foundation Model for Wireless Baseband Signal Spectrograms
Namhyun Kim, Sadjad Alikhani, Ahmed Alkhateeb
The received in-phase and quadrature (I/Q) baseband signals inherently encode physical-layer and channel characteristics of wireless links. Learning robust and transferable represe…
