Classical Capacity of A Quantum Multiple Access Channel
, 2000 We consider the transmission of classical information over a quantum channel by two senders. The channel capacity region is shown to be a convex hull bound by the Von Neumann entropy and the conditional Von Neumann entropy.

The Arbitrarily Varying Multiple-Access Channel with Conferencing Encoders
, 2012 We derive the capacity region of arbitrarily varying multiple-access channels with conferencing encoders for both deterministic and random coding. For a complete description it is sufficient that one conferencing capacity is positive.

Polar codes for the two-user multiple-access channel
, 2010 Arikan's polar coding method is extended to two-user multiple-access channels. It is shown that if the two users of the channel use the Arikan construction, the resulting channels will polarize to one of five possible extremals, on each of which uncoded ...

Multiple Access Relay Channel With Relay-Sources Feedback
IEEE Access, 2018 Feedback analysis on the rate region of multi-user channels is a problem of great importance in information and communication theory. In this paper, the Slepian-Wolf multiple access relay channel (SW-MARC) with relay-sources feedback is studied as a more

LDPC Codes over Gaussian Multiple Access Wiretap Channel
, 2018 We study the problem of two-user Gaussian multiple access channel (GMAC) in the presence of an external eavesdropper. In this problem, an eavesdropper receives a signal with a lower signal-to-noise ratio (SNR) compared to the legitimate receiver and all ...
