Bounds on Sphere Sizes in the Sum-Rank Metric and Coordinate-Additive Metrics
Hugo Beeloo-Sauerbier Couvée, Thomas Jerkovits, Jessica Bariffi
This paper provides new bounds on the size of spheres in any coordinate-additive metric with a particular focus on improving existing bounds in the sum-rank metric. We derive impro…

Support-Guessing Decoding Algorithms in the Sum-Rank Metric
Thomas Jerkovits, Hannes Bartz, Antonia Wachter-Zeh
The sum-rank metric generalizes the Hamming and rank metric by partitioning vectors into blocks and defining the total weight as the sum of the rank weights of these blocks, based…
