Some New Results on the Multiple-AccessWiretap Channel [PDF]
Entropy, 2014 In this paper, some new results on the multiple-access wiretap channel (MAC-WT) are provided. Specifically, first, we investigate the degraded MAC-WT, where two users transmit their corresponding confidential messages (no common message) to a legitimate ...

Multiple Access Channel Simulation [PDF]
2021 IEEE International Symposium on Information Theory (ISIT), 2021 We study the problem of simulating a two-user multiple-access channel (MAC) over a multiple access network of noiseless links. Two encoders observe independent and identically distributed (i.i.d.) copies of a source random variable each, while a decoder observes i.i.d. copies of a side-information random variable.

A simple Encoding Scheme to Achieve the Capacity of Half-Duplex Relay Channel
Advances in Electrical and Electronic Engineering, 2022 In this paper, the Half-Duplex Relay Channel (HDRC) is thoroughly investigated. Even though this channel model is widely studied, the capacity is not yet fully understood and particularly has not been tightly expressed.

Secrecy Rate Region Enhancement in Multiple Access Wiretap Channel
Journal of Telecommunications and Information Technology, 2022 It is commonly known that physical layer security is achieved with a trade-off in terms of the achievable rate. Hence, security constraints generate rate losses in wiretap channels.

The neural multiple access channel [PDF]
Neurocomputing, 2003 In many neural systems, independently encoded information must at some point be transmitted over the spike train of one neuron. We introduce a method for quantitatively studying the effects of the signal encoding and transmission processes on the rates of transmission of multiple sources of information over one spike train, using the multiple access ...

The Poisson multiple-access channel [PDF]
IEEE Transactions on Information Theory, 1998 The Poisson multiple-access channel (MAC) models many-to-one optical communication through an optical fiber or in free space. For this model we compute the capacity region for the two-user case as a function of the allowed peak power. Focusing on the maximum throughput we generalize our results to the case where the users are subjected to an additional

New Bounds on Capacity Region of Multiple Access Channels in Visible Light Communications
Entropy, 2022 In this paper, we propose new inner and outer bounds of the capacity region for multiple access channels in visible light communication (VLC) networks under both peak and average optical power constraints.

Playing games with multiple access channels [PDF]
Nature Communications, 2020 AbstractCommunication networks have multiple users, each sending and receiving messages. A multiple access channel (MAC) models multiple senders transmitting to a single receiver, such as the uplink from many mobile phones to a single base station.

Secrecy over Multiple-Access Channel: A Game of Competition and Cooperation [PDF]
Journal of Universal Computer Science, 2019 Communication networks have had a transformative impact on our society as they have revolutionized almost all aspects of human interaction. The explosive growth of data traffic has led to an increased demand on improving the reliability, efficiency and ...

The Broadcast Approach in Communication Networks
Entropy, 2021 In this paper we review the theoretical and practical principles of the broadcast approach to communication over state-dependent channels and networks in which the transmitters have access to only the probabilistic description of the time-varying states ...
