Deep Learning for Joint Narrowband Interference Cancellation and Soft Demodulation in OFDM Systems

Read the original on arXiv Machine Learning →

arXiv:2607. 08717v1 Announce Type: new Abstract: Narrowband interference (NBI) severely degrades orthogonal frequency-division multiplexing (OFDM) systems by corrupting subcarriers and rendering classical soft demodulation ineffective.

EqDeepRx: Learning a Scalable and Interference Mitigating MIMO Receiver

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.

Clearing the Underbrush: AI-Enhanced RF Interference Suppression

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.

CRFCAN: A Complex-Valued Cross-Domain Residual Network for Joint Channel and Phase Noise Estimation in Sub-THz OFDM Systems

CRFCAN is a complex‑valued residual FFT convolutional attention network that jointly estimates channel and phase noise in sub‑THz OFDM systems. It embeds FFT and inverse FFT modules within residual groups to enable iterative feature interaction across time and frequency domains, and includes dedicated residual blocks for complex feature extraction and multiplicative phase‑distortion modeling. Simulation results show that CRFCAN outperforms conventional algorithms and state‑of‑the‑art deep learning models in NMSE and BER, while offering single‑shot, fixed‑complexity inference and good generalization to unseen phase‑noise models.
