Digital-domain self-interference cancellation is essential in in-band full-duplex radios after passive suppression and analog cancellation. It is particularly challenging when the desired signal is st...
The paper presents an AI‑enhanced method for radio frequency interference suppression that builds on autoregressive transformer models by adding a Finite Scalar Quantization tokenizer layer. This addition improves interference rejection while maintaining low latency, and the authors also test other inference optimizations to speed up processing with minimal accuracy loss. Experiments using a digitally modulated RF signal as the signal of interest and a digital television OFDM signal as interference show that the approach outperforms traditional techniques and prior AI methods, with benefits demonstrated through audio quality metrics like PESQ and potential operational applications.

arXiv:2602. 11834v2 Announce Type: replace-cross Abstract: While machine learning (ML)-based receiver algorithms have received a great deal of attention in the recent literature, they often suffer from poor scaling with increasing spatial multiplexing order and lack of explainability and generalization.
