Coding Theory
On Multifold MDS and Perfect Codes That Are Not Splittable into Onefold Codes
D. S. Krotov, V. N. Potapov Sobolev Institute of Mathematics, Siberian Branch of the Russian Academy of Sciences
Abstract:
The union of $l$ disjoint MDS (or perfect) codes with distance 2 (respectively, 3) is always an $l$-fold MDS (perfect) code. The converse is shown to be incorrect. Moreover, if $k$ is a multiple of 4 and $n+1\geq 16$ is a power of two, then a $k/2$-fold $k$-ary MDS code of length $m\geq 3$ and an $(n+1)/8$-fold perfect code of length $n$ exist from which no MDS (perfect) code can be isolated.
