Dynamic Power Allocation Games in Parallel Multiple Access Channels [PDF]
, 2010 We analyze the distributed power allocation problem in parallel multiple access channels (MAC) by studying an associated non-cooperative game which admits an exact potential.

Random access over multiple access channels: A queuing perspective [PDF]
2008 42nd Annual Conference on Information Sciences and Systems, 2008 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.

Asynchronous multiple-access channel capacity [PDF]
IEEE Transactions on Information Theory, 1981 The capacity region for the discrete memoryless multiple-access channel without time synchronization at the transmitters and receivers is shown to be the same as the known capacity region for the ordinary multiple-access channel. The proof utilizes time sharing of two optimal codes for the ordinary multiple-access channel and uses maximum likelihood ...

Two-Stage Non-Orthogonal Multiple Access Over Power Line Communication Channels
IEEE Access, 2018 Non-orthogonal multiple access (NOMA) has recently been proposed for dual-hop cooperative relaying power line communication (PLC) systems. Unlike conventional NOMA-PLC schemes which deploy NOMA only at the relay, this paper proposes to enhance the ...

Random Beam-Based Non-Orthogonal Multiple Access for Low Latency K-User MISO Broadcast Channels
Sensors, 2021 In this paper, we propose random beam-based non-orthogonal multiple access (NOMA) for low latency multiple-input single-output (MISO) broadcast channels, where there is a target signal-to-interference-plus-noise power ratio (SINR) for each user.

N-DCF: MAC overhead reduction using narrow channel contention in wireless networks
EURASIP Journal on Wireless Communications and Networking, 2018 This paper presents a medium access control protocol for wireless networks that improves system spectral efficiency using multiple channels. Use of multiple narrow channels has already been proposed as a solution to reduce MAC overhead, but merely ...

Nearest Neighbor Decoding and Pilot-Aided Channel Estimation for Fading Channels
Entropy, 2020 We study the information rates of noncoherent, stationary, Gaussian, and multiple-input multiple-output (MIMO) flat-fading channels that are achievable with nearest neighbor decoding and pilot-aided channel estimation.

Entanglement-assisted capacity regions and protocol designs for quantum multiple-access channels
npj Quantum Information, 2021 We solve the entanglement-assisted (EA) classical capacity region of quantum multiple-access channels (MACs) with an arbitrary number of senders. As an example, we consider the bosonic thermal-loss MAC and solve the one-shot capacity region enabled by an
