WavesFM v1.0

Summary

WavesFM is a multimodal wireless foundation model for IQ streams and image-like modalities (spectrograms, CSI), plus CIR. It uses a ViT backbone with modality-specific input embeddings and a masked wireless modeling objective.

Model Details

• Architecture: ViT encoder + modality-specific input embeddings + lightweight task heads.
• Modalities: IQ, spectrograms, CSI, CIR.
• Objective: masked wireless modeling (MAE-style reconstruction).

• Reproduce: wavesfm.waveslab.ai/docs/reproduce
• GitHub: github.com/AhmedTarek62/wavesfm
• Quickstart notebook: wavesfm_demo.ipynb

Intended Use

• Research on multimodal wireless representation learning.
• Fine-tuning on downstream wireless tasks.

Downstream Tasks

• RF fingerprinting (IQ)
• Interference detection/classification (IQ)
• Human activity sensing (CSI)
• RF signal classification (spectrograms)
• 5G NR positioning (CSI)
• DeepMIMO LoS/NLoS and beam prediction (CSI)
• RADCOM signal/modulation classification (IQ)
• UWB indoor and industrial localization (CIR)
