Learning to Interfere in Non-Orthogonal Multiple-Access Joint Source-Channel Coding

Read the original on arXiv Machine Learning →

The paper proposes a machine‑learning–based wireless image transmission scheme that merges compression and channel coding via a multi‑view autoencoder, enabling multiple transmitters to share the same channel resources simultaneously in a non‑orthogonal multiple‑access (NOMA) setting. A progressive fine‑tuning algorithm doubles the number of users at each iteration while preserving orthogonalized performance, allowing the system to support up to 64 users with only a 2.4 % increase in trainable parameters. The method improves recovered image quality and outperforms existing NOMA‑based approaches across various datasets, metrics, and channel conditions.

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.

Deep Learning-Based Multi-User Communication Design for Dense IoT Networks: Interference-Aware Finite-Blocklength Communication and Preliminary MIMO Extensions

The paper presents a deep‑learning‑based end‑to‑end multi‑user communication design for dense IoT networks operating under interference‑limited, finite‑blocklength conditions. It extends a 2‑user SiameseNet transceiver to support 2, 4, and 8 users, using learned redundancy to suppress interference and improve noise robustness without joint detection. Preliminary results also show potential for a 2×2 MIMO configuration with fixed‑channel CSIT and CSIR.

Joint Semantic-Channel Coding and Modulation for Generative Image Transmission

The paper introduces SemQAM, a joint semantic-channel coding and modulation framework for generative image transmission that converts source representations directly into modulated QAM symbols. By vector‑quantizing latent features and mapping each index to a QAM symbol, SemQAM allows channel impairments to influence codebook learning and employs conditional expectations of received codewords to mitigate error propagation in autoregressive decoding. Experiments demonstrate that SemQAM-C matches or surpasses conventional source coding methods while reducing channel uses by 18.57% compared to separated schemes, highlighting its efficiency and effectiveness in joint coding.
