Multiple Access Channels with State Information Known at Some Encoders
A multiple access channel (MAC) with channel state information (CSI) non-causally known at some encoders is considered. For simplicity of exposition, a two-encoder model in which one of the encoders is non-causally informed of the CSI is focused. The results can in principle be extended to any number of encoders with a subset of them being informed. Inner and outer bounds for the capacity regio...
متن کاملOn Multiple User Channels with Causal State Information at the Transmitters
We extend Shannon’s result on the capacity of channels with state information to multiple user channels. More specifically, we characterize the capacity (region) of degraded broadcast channels and physically degraded relay channels where the channel state information is causally available at the transmitters. We also obtain inner and outer bounds on the capacity region for multiple access chann...
متن کاملFinite State Multiple-Access Wiretap Channel with Delayed Feedback
Recently, the finite state Markov channel (FSMC) with an additional eavesdropper and delayed feedback from the legitimate receiver to the transmitter has been shown to be a useful model for the physical layer security of the practical mobile wireless communication systems. In this paper, we extend this model to a multiple-access situation (up-link of the wireless communication systems), which w...
متن کاملOn the Capacity of Multiple Access Channels with State Information and Feedback
In this paper, the multiple access channel (MAC) with channel state is analyzed in a scenario where a) the channel state is known non-causally to the transmitters and b) there is perfect causal feedback from the receiver to the transmitters. An achievable region and an outer bound are found for a discrete memoryless MAC that extend existing results, bringing together ideas from the two separate...
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...
