Low-Complexity Learning-Based Beamforming for Ultra-Massive MIMO THz Communications
Sourabh Solanki, Abuzar Babikir Mohammad Adam, Chandan Kumar Sheemar +4
Terahertz (THz) communications have emerged as a key technology for escalating data rates in future generation wireless networks. However, severe propagation losses at THz frequenc…
Neural Precoding in Complex Projective Spaces
Zaid Abdullah, Merouane Debbah, Symeon Chatzinotas +1
Deep-learning (DL)-based precoding in multi-user multiple-input single-output (MU-MISO) systems involves training DL models to map features derived from channel coefficients to lab…
Swarm Intelligence Optimization of Multi-RIS Aided MmWave Beamspace MIMO
Zaid Abdullah, Mario R. Camana, Abuzar B. M. Adam +3
We investigate the performance of a multiple reconfigurable intelligence surface (RIS)-aided millimeter wave (mmWave) beamspace multiple-input multiple-output (MIMO) system with mu…
Multi-Active RIS-Assisted THz Cell-Free Systems: Spectral and Energy Efficiency Tradeoff
Mario R. Camana, Zaid Abdullah, Carla E. Garcia +3
Reconfigurable intelligent surfaces (RISs) and cell-free massive multiple-input multiple-output (CF-mMIMO) are effective solutions for mitigating large path loss and inter-cell int…
