Joint Subcarrier Allocation and Beamforming Optimization for IRS‐Assisted Multiuser MISO‐OFDMA Systems

open access: yesTransactions 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 ...
