On the Concatenated Code Constructions for Slotted Multiuser Communication Channel

In this paper we investigate a multiuser vector-disjunctive channel where users transmit binary vectors of length $$L$$ . Previously the capacity of this channel was estimated and it was shown that there are some cases when it achieves on non-uniform input distributions. This fact motivates us to investigate concatenated code constructions that allow us to reach target input distribution and detect or correct some error patterns appearing due to user interference or channel noise.
