Performance Enhancement of Cell Edge Users in NOMA Based Systems Using Fractional Frequency Reuse
Journal of Sensors, Volume 2026, Issue 1, 2026.Nonorthogonal multiple access (NOMA) causes significant performance loss for cell‐edge users due to strong intercell interference and fairness constraints under dense deployments. Although fractional frequency reuse (FFR) to improve dependability, especially for cell‐edge users, is widely researched, joint optimization with SINR‐based zoning and NOMA ...

Transactions on Emerging Telecommunications Technologies, Volume 36, Issue 7, July 2025.We introduce a novel model of an IRS‐assisted MU‐MISO‐OFDMA system. We aim to jointly optimize beamforming vectors, IRS reflection coefficients, and OFDM subcarrier allocation to maximize the overall sum rate. ABSTRACT In this article, we propose a novel resource allocation strategy for multiuser multiple‐input single‐output orthogonal frequency ...
