摘要:
We give an upper bound that relates the dimensions of some given number of linear codes, with the minimum distance of their componentwise product. A typical result is as follows: given t linear codes C-i of parameters [n, k(i)](q) with full support, one can find codewords c(i) epsilon C-i such that 1 <= w(c(1) * ... * c(t)) <= max(t = 1, n + t - (k(1) + ... + k(t))).
