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…

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…
