Cognition and Cooperation in Interfered Multiple Access Channels

open access: yesEntropy, 2017
In this work, we investigate a three-user cognitive communication network where a primary two-user multiple access channel suffers interference from a secondary point-to-point channel, sharing the same medium. While the point-to-point channel transmitter—

A Jamming-Resilient and Scalable Broadcasting Algorithm for Multiple Access Channel Networks

open access: yesApplied Sciences, 2021
Multiple access channel (MAC) networks use a broadcasting algorithm called the Binary Exponential Backoff (BEB) to mediate access to the shared communication channel by competing nodes and resolve their collisions.

On Achievable Rate Region of Multiple Coordinated Multiple Access Channels [PDF]

open access: yes, 2011
Coordination between two or more multiple access channel (MAC) receivers can enlarge the achievable rate region of the whole system. This paper focuses on coordination by sharing the codebooks of the users between the receivers of MACs.

Multiple Access Channels With Full-Duplex Amplify-and-Forward Transmitter Cooperations

open access: yesIEEE Access, 2019
In this paper, a full-duplex (FD) transmitter cooperative scheme is proposed to improve the achievable rate for multiple access channels (MACs). In the proposed scheme, by leveraging the FD amplify-and-forward (AF) protocol, two FD transmitters send ...

On Capacity Regions of Discrete Asynchronous Multiple Access Channels [PDF]

open access: yes, 2014
A general formalization is given for asynchronous multiple access channels which admits different assumptions on delays. This general framework allows the analysis of so far unexplored models leading to new interesting capacity regions.
