Massive MIMO Relaying with Hybrid Processing
Milad Fozooni, Michail Matthaiou, Shi Jin +1
Massive multiple-input multiple-output (MIMO) relaying is a promising technological paradigm which can offer high spectral efficiency and substantially improved coverage. Yet, thes…
Bit Error Rate Analysis of Cooperative Beamforming for Transmitting Individual Data Streams
Spyridon Vassilaras, George C. Alexandropoulos, Antonis A. Kalis
Cooperative beamforming (CB) has been proposed as a special case of coordinated multi-point techniques in wireless communications. In wireless sensor networks, CB can enable low po…
Maximal Ratio Transmission in Wireless Poisson Networks under Spatially Correlated Fading Channels
George C. Alexandropoulos, Marios Kountouris
The downlink of a wireless network where multi-antenna base stations (BSs) communicate with single-antenna mobile stations (MSs) using maximal ratio transmission (MRT) is considere…
Green Cognitive Relaying: Opportunistically Switching Between Data Transmission and Energy Harvesting
Nikolaos I. Miridakis, Theodoros A. Tsiftsis, George C. Alexandropoulos +1
Energy efficiency has become an encouragement, and more than this, a requisite for the design of next-generation wireless communications standards. In current work, a dual-hop cogn…
Apply Artificial Noise To Secure Fading Relay Networks: A SER-Based Approach
Ying Liu, Liang Li, George C. Alexandropoulos +1
We apply the concept of artificial and controlled interference in a triangular relay network with an untrusted relay aiming at enhancing the wireless communication secrecy between…
