Jamming Detection in Massive MIMO Systems
Hossein Akhlaghpasand, S. Mohammad Razavizadeh, Emil Björnson +1
This paper considers the physical layer security of a pilot-based massive multiple-input multiple-output (MaMIMO) system in presence of a multi-antenna jammer. To improve security…
Impact of User Height on the Coverage of 3D Beamforming-Enabled Massive MIMO Systems
M. Baianifar, S. Khavari, S. M. Razavizadeh +1
In this paper, we perform a coverage analysis of a cellular massive multiple-input multiple-output (MaMIMO) network which adopts 3D beamforming. In contrast to the previous works o…
Enhancement of Physical Layer Security Using Destination Artificial Noise Based on Outage Probability
Ali Rahmanpour, Vahid T. Vakili, S. Mohammad Razavizadeh
In this paper, we study using Destination Artificial Noise (DAN) besides Source Artificial Noise (SAN) to enhance physical layer secrecy with an outage probability based approach.…
Energy Efficient Precoding Design for SWIPT in MIMO Two-Way Relay Networks
Javane Rostampoor, S. Mohammad Razavizadeh, Inkyu Lee
In this paper, we study the energy efficiency (EE) maximization problem in multiple-input multiple-output (MIMO) two-way relay networks with simultaneous wireless information and p…
Jamming-Resistant Receivers for the Massive MIMO Uplink
Tan Tai Do, Emil Björnson, Erik G. Larsson +1
We design a jamming-resistant receiver scheme to enhance the robustness of a massive MIMO uplink system against jamming. We assume that a jammer attacks the system both in the pilo…
Resource Allocation and Relay Selection In Full-Duplex Cooperative Orthogonal Frequency Division Multiple Access Networks
Jafar Banar, S. Mohammad Razavizadeh
This paper is on relay selection in uplink of an in-band full-duplex (IBFD) cooperative cellular network. Assuming an orthogonal frequency division multiple access (OFDMA) cellular…
Joint Tilt Angle Adaptation and Beamforming in Multicell Multiuser Cellular Networks
Soheil Khavari Moghaddam, S. Mohammad Razavizadeh
3D beamforming is a promising approach for interference coordination in cellular networks which brings significant improvements in comparison with conventional 2D beamforming techn…
