Summary:It is shown that the encoding/decoding problem for any
asynchronous M-user discrete memoryless multiple-access channel can be
reduced to corresponding problems for at most 2M-1 single-user discrete
memoryless channels. This result, which extends a similar result for
Gaussian channels, reduces the seemingly hard task of finding good
multiple-access codes to the much better understood task of finding good
codes for single-user channels. As a by-product, some interesting
properties of the capacity region of M-user asynchronous discrete
memoryless channels are derived
