Joint Antenna Selection and Proportional Fairness User Scheduling for Multi-User Massive MIMO Systems
Published 2025-04-01“…However, it requires each antenna to be paired with a separate radio frequency (RF) chain, which leads to the need for numerous RF chains in the system, resulting in high hardware costs, increased computational complexity, and elevated power consumption. To address this, antenna selection technology reduces the number of RF chains required, activating only the antennas that correspond to the available RF chains. …”
