Multiple access channel with partial-cribbing encoders Conference Paper uri icon

abstract

  • In this paper we consider the multiple access channel (MAC) with partial cribbing encoders which means that each encoder obtains a deterministic function of the other encoder output, possibly with delay. The partial cribbing is especially motivated by the additive noise gaussian MAC since perfect cribbing results in the degenerated case of full cooperation between the encoders and requires an infinite entropy link. We derive a single letter characterization of the capacity of MAC with partial cribbing for the cases of causal and strictly causal partial cribbing.
