Moderate-density parity-check codes from projective bundles Autor Bariffi, Jessica, Mattheus, Sam, Neri, Alessandro, Rosenthal, Joachim

“… A projective bundle is a special collection of ovals which pairwise meet in a unique point. We determine the minimum distance and the dimension of these codes, and we show that they have a natural quasi-cyclic structure…”
