WebThe weight distributions of the proposed codes with one weight and with three weights are determined. In addition, we discuss the minimum distance of the dual of the constructed codes and show that some of them achieve the sphere packing bound. Moreover, examples show that some codes in this paper have best-known parameters.
Weband the distance function d is symmetric, then the bound ˝(H(G,r)) coincides with the sphere packing bound, that is, ˝ II. D(H(G,r)) = jXj r. Therefore, in this work the bound ˝(H(G,r)) is called the generalized sphere packing bound. The expression ˝(H(G,r)) provides an explicit upper bound on AG(n,2r + 1).
