The Gaussian Multiple Access Diamond Channel [PDF]
IEEE Transactions on Information Theory, 2011 In this paper, we study the capacity of the diamond channel. We focus on the special case where the channel between the source node and the two relay nodes are two separate links with finite capacities and the link from the two relay nodes to the destination node is a Gaussian multiple access channel.

On Multiple-Access in Queue-Length Sensitive Systems
IEEE Open Journal of the Communications Society, 2020 We consider transmission of packets over queue-length sensitive unreliable links, where packets are randomly corrupted through a noisy channel whose transition probabilities are modulated by the queue-length.

On a multiple-access in a vector disjunctive channel [PDF]
2013 IEEE International Symposium on Information Theory, 2013 We address the problem of increasing the sum rate in a multiple-access system from [1] for small number of users. We suggest an improved signal-code construction in which in case of a small number of users we give more resources to them. For the resulting multiple-access system a lower bound on the relative sum rate is derived.

A Formulation of the Channel Capacity of Multiple-Access Channel [PDF]
IEEE Transactions on Information Theory, 2009 The necessary and sufficient condition of the channel capacity is rigorously formulated for the N-user discrete memoryless multiple-access channel (MAC). The essence of the formulation is to invoke an {\em elementary} MAC where sizes of input alphabets are not greater than the size of output alphabet.

Analysis of factors affecting the operation of the communication system with nonorthogonal multiple access [PDF]
ITM Web of Conferences, 2019 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].
