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…
Generative Decompression: Optimal Lossy Decoding Against Distribution Mismatch
Saeed R. Khosravirad, Ahmed Alkhateeb, Ingrid van de Voorde
This paper addresses optimal decoding strategies in lossy compression where the assumed distribution for compressor design mismatches the actual (true) distribution of the source.…
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…
