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…
Pinching Antenna Systems versus Reconfigurable Intelligent Surfaces in mmWave
Mostafa Samy, Hayder Al-Hraishawi, Madyan Alsenwi +3
Flexible and intelligent antenna designs, such as pinching antenna systems and reconfigurable intelligent surfaces (RIS), have gained extensive research attention due to their pote…
SmartUT: Receive Beamforming for Spectral Coexistence of NGSO Satellite Systems
Almoatssimbillah Saifaldawla, Eva Lagunas, Flor Ortiz +2
In this paper, we investigate downlink co-frequency interference (CFI) mitigation in non-geostationary satellites orbits (NGSOs) co-existing systems. Traditional mitigation techniq…
Low-Complexity Channel Estimation Protocol for Non-Diagonal RIS-Assisted Communications
Mostafa Samy, Hayder Al-Hraishawi, Abuzar B. M. Adam +3
Non-diagonal reconfigurable intelligent surfaces (RISs) offer enhanced wireless signal manipulation over conventional RIS by enabling the incident signal on any of its elements…
