User-Centric Distributed Antenna Transmission: Secure Precoding and Antenna Selection with Interference Exploitation
Zhongxiang Wei, Christos Masouros
We address physical layer security in distributed antenna (DA) systems, where eavesdroppers (Eves) can intercept the information transmitted for the intended receiver (IR). To real…
Sum Rate and Fairness Analysis for the MU-MIMO Downlink under PSK Signalling: Interference Suppression vs Exploitation
Abdelhamid Salem, Christos Masouros, Kai-Kit Wong
In this paper, we analyze the sum rate performance of multi-user multiple-input multiple-output (MU-MIMO) systems, with a finite constellation phase-shift keying (PSK) input alphab…
Interference Exploitation Precoding for Multi-Level Modulations: Closed-Form Solutions
Ang Li, Christos Masouros, Yonghui Li +2
In this paper, we study closed-form interference-exploitation precoding for multi-level modulations in the downlink of multi-user multiple-input single-output (MU-MISO) systems. We…
Hybrid Analog-Digital Precoding for Interference Exploitation
Ang Li, Christos Masouros, Fan Liu
We study the multi-user massive multiple-input-single-output (MISO) and focus on the downlink systems where the base station (BS) employs hybrid analog-digital precoding with low-c…
1-Bit Massive MIMO Downlink Based on Constructive Interference
Ang Li, Christos Masouros, A. Lee Swindlehurst
In this paper, we focus on the multiuser massive multiple-input single-output (MISO) downlink with low-cost 1-bit digital-to-analog converters (DACs) for PSK modulation, and propos…
Hybrid Beamforming With Sub-arrayed MIMO Radar: Enabling Joint Sensing and Communication at mmWave Band
Fan Liu, Christos Masouros
In this paper, we propose a beamforming design for dual-functional radar-communication (DFRC) systems at the millimeter wave (mmWave) band, where hybrid beamforming and sub-arrayed…
Interference Exploitation-based Hybrid Precoding with Robustness Against Phase Errors
Ganapati Hegde, Christos Masouros, Marius Pesavento
Hybrid analog-digital precoding significantly reduces the hardware costs in massive MIMO transceivers when compared to fully-digital precoding at the expense of increased transmit…
Interfering Channel Estimation in Radar-Cellular Coexistence: How Much Information Do We Need?
Fan Liu, Adrian Garcia-Rodriguez, Christos Masouros +1
In this paper, we focus on the coexistence between a MIMO radar and cellular base stations. We study the interfering channel estimation, where the radar is operated in the "search…
Deployment Strategies of Multiple Aerial BSs for User Coverage and Power Efficiency Maximization
Jingcong Sun, Christos Masouros
Unmanned aerial vehicle (UAV) based aerial base stations (BSs) can provide rapid communication services to ground users and are thus promising for future communication systems. In…
