Constructive Interference Based Secure Precoding: A New Dimension in Physical Layer Security
Muhammad R. A. Khandaker, Christos Masouros, Kai-Kit Wong
Conventionally, interference and noise are treated as catastrophic elements in wireless communications. However, it has been shown recently that exploiting known interference const…
Robust MIMO Beamforming for Cellular and Radar Coexistence
Fan Liu, Christos Masouros, Ang Li +1
In this letter, we consider the coexistence and spectrum sharing between downlink multi-user multiple-input-multiple-output (MU-MIMO) communication and a MIMO radar. For a given pe…
Transmit Beamforming for Interference Exploitation in the Underlay Cognitive Radio Z-channel
Ka Lung Law, Christos Masouros, Marius Pesavento
This paper introduces novel transmit beamforming approaches for the cognitive radio (CR) Z-channel. The proposed transmission schemes exploit non-causal information about the inter…
Reduced Switching Connectivity for Large Scale Antenna Selection
Adrian Garcia-Rodriguez, Christos Masouros, Pawel Rulikowski
In this paper, we explore reduced-connectivity radio frequency (RF) switching networks for reducing the analog hardware complexity and switching power losses in antenna selection (…
Hybrid Analog-Digital Precoding Revisited under Realistic RF Modeling
Adrian Garcia-Rodriguez, Vijay Venkateswaran, Pawel Rulikowski +1
In this paper we revisit hybrid analog-digital precoding systems with emphasis on their modelling and radio-frequency (RF) losses, to realistically evaluate their benefits in 5G sy…
On the Spectral Efficiency of Space-Constrained Massive MIMO with Linear Receivers
Jiayi Zhang, Linglong Dai, Michail Matthaiou +2
In this paper, we investigate the spectral efficiency (SE) of massive multiple-input multiple-output (MIMO) systems with a large number of antennas at the base station (BS) account…
