The Second Order Scattering Fading Model with Fluctuating Line-of-Sight
Jesus Lopez-Fernandez, Gonzalo J. Anaya-Lopez, F. Javier Lopez-Martinez
We present a generalization of the notoriously unwieldy second-order scattering fading model, which is helpful to alleviate its mathematical complexity while providing an additiona…
Leakage Subspace Precoding and Scheduling for Physical Layer Security in Multi-User XL-MIMO Systems
Gonzalo J. Anaya-Lopez, Jose P. Gonzalez-Coma, F. Javier Lopez-Martinez
We investigate the achievable secrecy sum-rate in a multi-user XL-MIMO system, on which user distances to the base station become comparable to the antenna array dimensions. We sho…
A New Transmit Antenna Selection Technique for Physical Layer Security with Strong Eavesdropping
Gonzalo J. Anaya-López, J. Carlos Ruiz-Sicilia, F. Javier López-Martínez
We propose a new transmit antenna selection (TAS) technique that can be beneficial for physical layer security purposes. Specifically, we show that the conventional TAS criterion b…
A Product Channel Attack to Wireless Physical Layer Security
Gonzalo J. Anaya-Lopez, Gerardo Gomez, F. Javier Lopez-Martinez
We propose a novel attack that compromises the physical layer security of downlink (DL) communications in wireless systems. This technique is based on the transmission of a slowly-…
