Quantum Multiple Access Channel

Chinese Physics Letters, 2001
We consider the transmission of classical information over a quantum channel by many senders, which is a generalization of the two-sender case. The channel capacity region is shown to be a convex hull bound by the von Neumann entropy and the conditional von Neumann entropies.

Channel-hopping multiple access

2000 IEEE International Conference on Communications. ICC 2000. Global Convergence Through Communications. Conference Record, 2002
The medium-access control (MAC) protocols for wireless networks proposed or implemented to date based on collision-avoidance handshakes between the sender and receiver either require carrier sensing or the assignment of unique codes to nodes to ensure that intended receivers hear data packets without interference from hidden sources.

Channel configuration of multiple-access channel

International Symposium onInformation Theory, 2004. ISIT 2004. Proceedings., 2004
This paper investigates the channel configuration of multiple-access channel (MAC) by decomposing the MAC into finite subMAC and also proves that there exists an input probability that achieves boundary of a capacity region and the total capacity of the original MAC.

Channel aware scheduling for multiple antenna multiple access channels

The Thrity-Seventh Asilomar Conference on Signals, Systems & Computers, 2003, 2004
In this paper, we study the optimum transmission strategy of the multiple access channel in a cellular system in which the base station has multiple antennas. Recently, scheduling algorithms incorporating both the physical and data link layer were proposed e.g. in H. Boche and M. Wiczanowski, (2003), M. J. Neely, et al., (Feb. 2003), E. M. Yeh, (2002),

Cognitive access algorithms for multiple access channels

2013 IEEE 14th Workshop on Signal Processing Advances in Wireless Communications (SPAWC), 2013
This paper considers a multiple access fading channel where each terminal has a different belief about the channel states and adapts its transmission policy to the belief. In this setting, frequency division multiple access (FDMA) and channel aware random access (RA) are two special cases.

Multiple Access Covert Channels

2005
Abstract : In this paper we consider the situation of multiple malicious transmitters attempting to covertly communicate with a single receiver, We show how the situation of non-collaborating transmitters can be modeled by multiple access channels. The simpler situation of collaborating transmitters is used as a bounding result.
