D.10.2.2 sysCRHTMindist
Procedure from library decodegb.lib (see decodegb_lib).
- Usage:
- sysCRHTMindist(n,defset,w); n,w are int, defset is list of int's
| - n length of the cyclic code,
- defset is a list representing the defining set,
- w is a candidate for the minimum distance
|
- Return:
- the ring to work with the Sala's ideal for the minimum distance
containing the ideal with name 'crht_md'
- Theory:
- Based on 'defset' of the given cyclic code, the procedure constructs
the corresponding Cooper-Reed-Heleseth-Truong ideal 'crht_md'. With
its help one can find minimum distance of the code in the binary
case. For basics of the method Cooper philosophy.
