Multiobjective Optimization of User-centric Performance Design in UAV-SATCOM-Enabled Cell-Free Massive MIMO Networks
摘要
We consider the downlink of a massive multiple-input multiple-output (mMIMO) system for cell-free networks where many dispersed Unmanned Aerial Vehicle-Satellite Communication (UAV-SATCOM) nodes (USCs) serve a few number of centric users under duplex operation with time division. A crucial concern while implementing cell-free mMIMO networks is the large amount of electricity consumed, which is proportional to the number of USCs. The topic is the usage of electricity green communications in terms of spectral efficiency has been brought up by this problem over multiobjective Quality of Service (QoS) per user. To address this issue, we create a brand-new low-complexity power management method with zero-forcing beamforming design to optimize the spectral efficiency of cell-free mMIMO taking into account the design of user-centric performance.
