RT info:eu-repo/semantics/article T1 Feng-Rao decoding of primary codes A1 Geil, Olav A1 Matsumoto, Ryutaroh A1 Ruano Benito, Diego AB We show that the Feng-Rao bound for dual codes and a similar bound by Andersen and Geil for primary codes are consequences of each other. This implies that the Feng-Rao decoding algorithm can be applied to decode primary codes up to half their designed minimum distance. The technique applies to any linear code for which information on well-behaving pairs is available. Consequently we are able to decode efficiently a large class of codes for which no non-trivial decoding algorithm was previously known. Among those are important families of multivariate polynomial codes. Matsumoto and Miura derived from the Feng-Rao bound a bound for primary one-point algebraic geometric codes and showed how to decode up towhat is guaranteed by their bound. The exposition in Matsumoto-Miura requires the useof differentials which was not needed in Andersen-Geil. Nevertheless we demonstrate a very strong connection between Matsumoto and Miura's bound and Andersen and Geil's bound when applied to primary one-point algebraic geometric codes.
