On the Transmit Beamforming for MIMO Wiretap Channels: Large-System Analysis
Maksym A. Girnyk, Frédéric Gabry, Mikko Vehkaperä +2
With the growth of wireless networks, security has become a fundamental issue in wireless communications due to the broadcast nature of these networks. In this work, we consider MI…
On the Optimal Precoding for MIMO Gaussian Wire-Tap Channels
Arash Khabbazibasmenj, Maksym A. Girnyk, Sergiy A. Vorobyov +2
We consider the problem of finding secrecy rate of a multiple-input multiple-output (MIMO) wire-tap channel. A transmitter, a legitimate receiver, and an eavesdropper are all equip…
Asymptotic Performance Analysis of a K-Hop Amplify-and-Forward Relay MIMO Channel
Maksym A. Girnyk, Mikko Vehkaperä, Lars K. Rasmussen
The present paper studies the asymptotic performance of multi-hop amplify-and-forward relay multiple-antenna communication channels. Each multi-antenna terminal in the network ampl…
Asymptotic Analysis of SU-MIMO Channels With Transmitter Noise and Mismatched Joint Decoding
Mikko Vehkaperä, Taneli Riihonen, Maksym A. Girnyk +4
Hardware impairments in radio-frequency components of a wireless system cause unavoidable distortions to transmission that are not captured by the conventional linear channel model…
