Homologous Codes for Multiple Access Channels [PDF]
IEEE Transactions on Information Theory, 2018 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 ...

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 ...

The mismatched multiple-access channel: General alphabets
2013 IEEE International Symposium on Information Theory, 2013 This paper considers channel coding for the memoryless multiple-access channel with a given (possibly suboptimal) decoding rule. Non-asymptotic bounds on the error probability are given, and a cost-constrained random-coding ensemble is used to obtain an achievable error exponent. The achievable rate region recovered by the error exponent coincides with

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.

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.

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 ...

Analysis of the Impact of Wireless Three-User Multiple Access Channel Coefficients Correlation on Outage Probability: A Copula-Based Approach [PDF]
Computer and Knowledge Engineering, 2023 In wireless communication channels, the channel coefficients are dependent on each other. This paper investigates the constructive or destructive effects of fading coefficients correlation of wireless multiple access channels (MAC) on the outage ...
