Each interference is known to exactly one transmitter non-causally. The capacity region is characterized to within a bounded gap regardless of channel parameters. These results are based on a layered modulo-lattice scheme which realizes distributed interference cancellation.Dirty multiple-access channels (MACs)dirty paper codingdistributed interference cancellationmodulo-lattice schemeLattice StrategiesApproximate Capacity of the Dirty Multiple-Access Channel With Partial State Information at the Encoderstext::journal::journal article::research article
