What happened
Collection of arXiv papers (24 Jun 2026) spanning communications, information theory, coding, and algorithms. Highlights: a low-complexity hybrid precoding framework for cell-free massive MU-MIMO ISAC systems that reduces fronthaul and baseband complexity and enforces sensing PEB constraints via an AO solver and multi-branch RS MMSE-THP updates; analysis of extension profiles and a shape function for joint random variable pairs linking information inequalities to spectral graph properties; MiLAC combiner study showing a zero-gap threshold of two RF chains per target to attain the fully-digital
