Deletion-Correcting Codes for the $\ell$-Symbol Read Channel

Collection of new arXiv submissions (Jun 26 2026) across coding theory, communications, and inference. Key contributions: structural characterization and constructions of deletion-correcting codes for the ℓ-symbol read channel (applications: nanopore sequencing, racetrack memories) with low-redundancy single- and multi-deletion schemes; a constant-modulus, low-PAPR non-coherent Grassmannian modulation with a phase-blind timing-error detector for optical links; a measured-radiation-pattern-aware design and coupling-efficiency optimization for pinching-antenna waveguide systems; tight lower-bnds
