OFDM-Based Active STAR-RIS-Aided Integrated Sensing and Communication Systems
Hanxiao Ge, Anastasios Papazafeiropoulos, Tharmalingam Ratnarajah
Simultaneously transmitting and reflecting reconfigurable intelligent surface (STAR-RIS), which consists of numerous passive elements, has recently emerged in wireless communicatio…
Joint Power Allocation and Beamforming for In-band Full-duplex Multi-cell Multi-user Networks
Haifeng Luo, Navneet Garg, Mark Holm +1
This paper investigates a robust joint power allocation and beamforming scheme for in-band full-duplex multi-cell multi-user (IBFD-MCMU) networks. A mean-squared error (MSE) minimi…
On the Secrecy Rate of In-Band Full-duplex Two-way Wiretap Channel
Navneet Garg, Haifeng Luo, Tharmalingam Ratnarajah
In this paper, we consider a two-way wiretap Multi-Input Multi-Output Multi-antenna Eve (MIMOME) channel, where both nodes (Alice and Bob) transmit and receive in an in-band full-d…
Two-Timescale Design for Active STAR-RIS Aided Massive MIMO Systems
Anastasios Papazafeiropoulos, Hanxiao Ge, Pandelis Kourtessis +3
Simultaneously transmitting and reflecting \textcolor{black}{reconfigurable intelligent surface} (STAR-RIS) is a promising implementation of RIS-assisted systems that enables full-…
Achievable Rate Optimization for Stacked Intelligent Metasurface-Assisted Holographic MIMO Communications
Anastasios Papazafeiropoulos, Jiancheng An, Pandelis Kourtessis +2
Stacked intelligent metasurfaces (SIM) is a revolutionary technology, which can outperform its single-layer counterparts by performing advanced signal processing relying on wave pr…
Degrees-of-Freedom Regions for -User MISO Time-Correlated Broadcast Channel
Yi Luo, Tharmalingam Ratnarajah, Anastasios K. Papazafeiropoulos
In this paper, we study the achievable degrees-of-freedom (DoF) regions of the -user multiple-input-single-output (MISO) time correlated broadcast channel (BC). The time correla…
