MAC with partially cooperating encoders and security constraints
We study a special case of Willems’s two-user multiaccess channel with partially cooperating encoders from security perspective. This model differs from Willems’s setup in that only one encoder, Encoder 1, is allowed to conference, Encoder 2 does not transmit any message, and there is an additional passive eavesdropper from whom the communication should be kept secret. For the discrete memoryle...
متن کاملThe Multiple Access Channel with Correlated Sources and Cribbing Encoders
A discrete memoryless multiple access channel (MAC) is a quadruple { X1,X2, PY |X1,X2 ,Y } where X1,X2 are the input alphabets, Y the output alphabet, and PY |X1,X2 a transition probability matrix from X1 × X2 to Y . For shorthand notation, we will refer to the MAC by PY |X1,X2 . A source pair is a triplet {U ,V, PU,V } where PU,V is a distribution on U × V . We use the following notation: rand...
متن کاملMultiple Access Channels with Cooperative Encoders and Channel State Information
cooperative encoders and Channel State Information (CSI) is considered where two different scenarios are investigated: A two-user MAC with common message (MACCM) and a two-user MAC with conferencing encoders (MACCE). For both situations, the two cases where the CSI is known to the encoders either non-causally or causally are studied. Achievable rate regions are established for both discrete mem...
متن کاملThe Classical-Quantum Multiple Access Channel with Conferencing Encoders and with Common Messages
We prove coding theorems for two scenarios of cooperating encoders for the multiple access channel with two classical inputs and one quantum output. In the first scenario (ccq-MAC with common messages), the two senders each have their private messages, but would also like to transmit common messages. In the second scenario (ccq-MAC with conferencing encoders), each sender has its own set of mes...
متن کاملThe Multiple Access Channel with Causal and Strictly Causal Side Information at the Encoders
We study the state-dependent multiple access channel (MAC) with causal side information at the encoders. We consider two general models. In the first model, the state sequence is available at the two encoders in a strictly causal manner. We derive an achievable region, which is tight for the special case of a Gaussian MAC where the state sequence comprises the channel noise. Although the two se...
