On reconstruction of a binary code from dimensions of its subcodes
Abstract:
Regarding q-ary codes, we generalize the theorem on reconstructing of a binary code from dimensions of its subcodes. The new reconstruction theorem involves arbitrary positive integer q. We propose he term of a correlation coefficient for a set of subcodes of a code. Here correlation coefficient of subcodes is a q-ary analog for dimension of a subcode of a binary code.
