Multiple access Gaussian channels with feedback
53rd IEEE Conference on Decision and Control, 2014We consider the problem of multiple access communication with feedback, and show that the well known schemes of Ozarow and Kramer may be represented as feedback systems with a marginally unstable decoder. Other approaches represent these schemes as feedback systems with a strictly unstable encoder.

On the capacity of multiplicative multiple access channels with AWGN
2011 IEEE Information Theory Workshop, 2011We consider a multiplicative multiple access channel in the presence of additive white Gaussian noise. Under individual average power constraints at each of the transmitters, we characterize the capacity region of this channel. The structure of the region reveals some fundamental characteristics related to timesharing, power constraints and the ...

The multiple access channel with an untrusted relay
2014 IEEE Information Theory Workshop (ITW 2014), 2014This paper considers a Gaussian multiple access channel aided by a relay. Specifically, the relay facilitates communication between multiple sources and a destination to which the sources have no direct link. In this set up, the relay node is considered to be untrusted, i.e., honest but curious, from whom the source messages need to be kept secret.

In the preceding three chapters, we develop and apply the compressed-error-cancellation framework to the single-user case, i.e., the situation in which a single transmitter must send data to a single receiver. But often in practice, multiple transmitters must simultaneously send data to multiple receivers.

Variations on the Gaussian Multiple-Access Channel
2007 IEEE International Symposium on Information Theory, 2007This paper studies two models derived from the Gaussian Multiple-Access Channel. In each, information is sent by energy modulation, rather than on the complex signal amplitude. For continuous energy, the model is the additive exponential noise (AEN) channel, whose capacity region equals that of the equivalent Gaussian channel at identical noise and ...

Resolvability theory for the multiple-access channel
IEEE Transactions on Information Theory, 1998Summary: We study the randomness needed for approximating the output distribution of a multiple-access channel, where the original input processes are independent of each other. The approximation is achieved by simulating (possibly alternative) input processes at each of the entries, where the sources of randomness available for the simulators are ...
