In this paper, line coding schemes and their application to the multiuser adder channel are investigated. The focus is on designing line codes with higher information per channel use rates than time- sharing. We show that by combining short multi-user line codes, it is possible to devise longer coding schemes with rate sums which increase quite rapidly at each iteration of the construction. Asymptotically, there is no penalty in requiring the coding schemes to be DC-free.
