The Interference-Multiple-Access Channel

2009 IEEE International Conference on Communications, 2009
We introduce the interference-multiple-access channel, which is a discrete memoryless channel with two transmitters and two receivers, similar to the interference channel. One receiver is required to decode the information encoded at one transmitter, the other receiver is required to decode the messages from both transmitters. We provide an inner bound

Adversarial queuing on the multiple-access channel

Proceedings of the twenty-fifth annual ACM symposium on Principles of distributed computing, 2006
We study deterministic broadcasting on multiple access channels when packets are injected continuously. The quality of service is considered in the framework of adversarial queuing. An adversary is determined by injection rate and burstiness, the latter denoting the number of packets that can be injected simultaneously in a round.

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.

On multiple access channels with feedback

IEEE Trans. Inf. Theory, 1984
Summary: For the binary erasure multiple access channel, \textit{E. C. van der Meulen} [ibid. IT-23, 1-37 (1977; Zbl 0355.94035)] showed in his survey paper that the symmetrical rate pair (0.79113, 0.79113) is achievable in the case of feedback. Here we prove that this rate point is on the boundary of the feedback capacity region. Subsequently we apply

A hybrid access method in a multiple access channel

Performance Evaluation, 1986
Abstract This paper considers a multiple-access communication channel with an infinite number of users. We show that if a controlled slotted Aloha protocol is used, then messages with variable length will have a negative impact on the average message delay.

The Cost of Synchronizing Multiple-Access Channels

Proceedings of the 2015 ACM Symposium on Principles of Distributed Computing, 2015
Multiple access channel is a communication model in which many users, also called stations, could exchange information. Since it offers limited capacity, some information sent through it might be lost due to signal interference (collision). Therefore, successful message delivery to a station requires breaking symmetry on the channel.

Multiple-Access Channels With Confidential Messages

IEEE Transactions on Information Theory, 2008
A discrete memoryless multiple-access channel (MAC) with confidential messages is studied, where two users attempt to transmit common information to a destination and each user also has private (confidential) information intended for the destination. This channel generalizes the classical MAC model in that each user also receives channel outputs, and ...

Multiple access Gaussian channels with feedback

53rd IEEE Conference on Decision and Control, 2014
We 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.

Decoding for multiple-access channels

2005
We discuss some results in coding and decoding for multiple-access channels. A new approach to choosing codes and users' energies for that channel is described. For the case when a bit error probability and a decoding complexity are fixed we construct a region of achievable code rates.
