Contextual Memory-Enhanced Source Coding for Low-SNR Communications

Batch of recent arXiv submissions (information theory / communications) covering new methods in source and channel coding, constellation design, distributed storage, compression of random graphs, encryption-theoretic source coding, antenna/array architectures, ISAC topologies, gossip-age analysis, private retrieval, and identification capacity. Key contributions include: a Memory-Augmented Source Coding (MASC) scheme (shared Parameterized Contextual Memory + Mixture-of-Memory-Experts Router) to make SSCC robust to residual channel errors and LLM-based probability estimation; S-Opt and Z-Opt 2D
