Model-based Deep Learning for Joint RIS Phase Shift Compression and WMMSE Beamforming
Alexander James Fernandes, Ioannis Psaromiligkos
A model-based deep learning (DL) architecture is proposed for reconfigurable intelligent surface (RIS)-assisted multi-user communications to reduce the number of bits required for…
Access Probability Optimization in RACH: A Multi-Armed Bandits Approach
Ahmed O. Elmeligy, Ioannis Psaromiligkos, Au Minh
The use of cellular networks for massive machine-type communications (mMTC) is an appealing solution due to the availability of the existing infrastructure. However, the massive nu…
Load Estimation in a Two-Priority mMTC Random Access Channel
Ahmed O. Elmeligy, Ioannis Psaromiligkos, Au Minh
The use of cellular networks for massive machine-type communications (mMTC) is an appealing solution due to the wide availability of cellular infrastructure. Estimating the number…
Channel Estimation for Reconfigurable Intelligent Surface MIMO with Tensor Signal Modelling
Alexander James Fernandes, Ioannis Psaromiligkos
We consider a narrowband MIMO reconfigurable intelligent surface (RIS)-assisted wireless communication system and use tensor signal modelling techniques to individually estimate al…
