Interference-Aware Super-Constellation Design for NOMA

no code implementations10 Mar 2025 Mojtaba Vaezi, Xinliang Zhang

Non-orthogonal multiple access (NOMA) has gained significant attention as a potential next-generation multiple access technique.

Selective Experience Sharing in Reinforcement Learning Enhances Interference Management

no code implementations27 Jan 2025 Madan Dahal, Mojtaba Vaezi

We propose a novel multi-agent reinforcement learning (RL) approach for inter-cell interference mitigation, in which agents selectively share their experiences with other agents.

Multi-Objective DNN-based Precoder for MIMO Communications

no code implementations6 Jul 2020 Xinliang Zhang, Mojtaba Vaezi

Numerical results demonstrate that, compared to the conventional solutions, the proposed DNN-based precoder reduces on-the-fly computational complexity more than an order of magnitude while reaching near-optimal performance (99. 45\% of the averaged optimal solutions).
