The local weight distribution is the weight distribution of zero neighbors in a code. A zero neighbor is a codeword whose Voronoi region shares a facet with that of the all-zero codeword. The local weight distribution is valuable
for an error performance analysis of the code. In this paper, some relations are shown for the local weight distributions of transitive invariant codes and their punctured codes. Extended primitive BCH codes and Reed-Muller codes are transitive invariant codes. Only-odd decomposable codewords are key codewords in those relations. A method for finding the only-odd decomposable codewords is also presented. |
