Direction-Based Jamming Detection and Suppression in mmWave Massive MIMO Networks
Saeed Bagherinejad1, S. Mohammad Razavizadeh
In this paper, we study the problem of physical layer security in the uplink of millimeter-wave massive multiple-input multiple-output (MIMO) networks and propose a jamming detecti…
Vertical Beamforming in Reconfigurable Intelligent Surface-aided Cognitive Radio Networks
S. Fatemeh Zamanian, S. Mohammad Razavizadeh, Qingqing Wu
In this letter, we investigate joint application of reconfigurable intelligent surface (RIS) and vertical beamforming in cognitive radio networks (CRN). After properly modeling the…
Deep Reinforcement Learning-based Anti-jamming Power Allocation in a Two-cell NOMA Network
Sina Yousefzadeh Marandy, Mohammad Ali Amirabadi, Mohammad Hossein Kahaei +1
The performance of Non-orthogonal Multiple Access (NOMA) system dramatically decreases in the presence of inter-cell interference. This condition gets more challenging if a smart j…
Spectral Efficiency of Dense Multicell Massive MIMO Networks in Spatially Correlated Channels
FahimeSadat Mirhosseini, Aliakbar Tadaion, S. Mohammad Razavizadeh
This paper is on the spectral efficiency (SE) of a dense multi-cell massive multiple-input multiple-output (MIMO). The channels are spatially correlated and the multi-slope path lo…
Secrecy Rate Maximization in Multi-IRS Millimeter Wave Networks
Anahid Rafieifar, S. Mohammad Razavizadeh
This paper investigates the problem of increasing the security at the physical layer of a Millimeter Wave (mmWave) network equipped with several Intelligent Reflecting Surfaces (IR…
Secure Simultaneous Information and Power Transfer for Downlink Multi-user Massive MIMO
Zahra Goli, S. Mohammad Razavizadeh, Hamed Farhadi +1
In this paper, downlink secure transmission in simultaneous information and power transfer (SWIPT) system enabled with massive multiple-input multiple-output (MIMO) is studied. A b…
