Abstract

A random coding bound for the multiple-access channel (MAC) is given, and it is shown to be obtainable universally for all MAC's with common input and output alphabets. For channels for which the random coding bound may be achieved by codes consisting of codewords of a single type for each sender, this bound is also achievable by codes produced by permutations.
