Cognition and Cooperation in Interfered Multiple Access Channels
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—

Homologous Codes for Multiple Access Channels [PDF]
Building on recent development by Padakandla and Pradhan, and by Lim, Feng, Pastore, Nazer, and Gastpar, this paper studies the potential of structured nested coset coding as a complete replacement for random coding in network information theory. The roles of two techniques used in nested coset coding to generate nonuniform codewords, namely, shaping ...

Compound Multiple-Access Channels With Partial Cooperation [PDF]
A two-user discrete memoryless compound multiple access channel with a common message and conferencing decoders is considered. The capacity region is characterized in the special cases of physically degraded channels and unidirectional cooperation, and achievable rate regions are provided for the general case.

Analysis of factors affecting the operation of the communication system with nonorthogonal multiple access [PDF]
NOMA is a group of non-orthogonal multiple access methods [1]. In this article, we talk about the Power Domain (Division) NOMA method. It is a non-orthogonal multiple access method with channel separation by power [2].

Random access over multiple access channels: A queuing perspective [PDF]
This paper investigates a slotted random access system where packet capture is modeled using communication theoretic techniques. It is shown that the optimum rates and attempt probabilities depend on the receiver architecture, operating signal-to-noise ratio (SNR) and block length.

Non‐orthogonal multiple access without channel state information for similar channel conditions
A downlink non‐orthogonal multiple access with QPSK input constellations based on virtual channel optimisation is presented to address the similar channel conditions scenario.

Polar Coding for the Multiple Access Channel With Confidential Messages
The multiple access channel with confidential messages (MAC-CM) generalizes the traditional multiple access channel by allowing both users to receive channel outputs.
