On the Security of Cell-Free Massive MIMO Networks. [PDF]
Sensors (Basel)The rapid growth of wireless devices, the expansion of the Internet of Things, and the aggregate demand for Ultra-Reliable Low-Latency communications (URLLC) are driving the improvement of next-generation wireless systems. One promising emerging technology in this area is cell-free massive Multiple Input Multiple Output (maMIMO) networks.

Cell-Free Massive MIMO Versus Small Cells [PDF]
IEEE Transactions on Wireless Communications, 2017 A Cell-Free Massive MIMO (multiple-input multiple-output) system comprises a very large number of distributed access points (APs)which simultaneously serve a much smaller number of users over the same time/frequency resources based on directly measured channel characteristics. The APs and users have only one antenna each.

Cell-Free Massive MIMO Surveillance Systems
GLOBECOM 2023 - 2023 IEEE Global Communications Conference, 2023 Wireless surveillance, in which untrusted communications links are proactively monitored by legitimate agencies, has started to garner a lot of interest for enhancing the national security. In this paper, we propose a new cell-free massive multiple-input multiple-output (CF-mMIMO) wireless surveillance system, where a large number of distributed multi ...

IET Networks, EarlyView., 2023 We utilise a metaheuristic optimisation method, inspired by nature, called the Lévy‐flight firefly algorithm (LFA), to tackle the power regulation and user grouping in the NOMA systems. Abstract The non‐orthogonal multiple access strategies have shown promise to boost fifth generation and sixth generation wireless networks' spectral efficiency and ...

Clustered Cell-Free Massive MIMO [PDF]
2018 IEEE Globecom Workshops (GC Wkshps), 2018 This paper introduces a novel technique, clustered cell-free massive-MIMO (C2F-M-MIMO), that generalizes the recently proposed cell-free massive MIMO (CF-M-MIMO) concept by optimizing the connectivity pattern among access points (APs) and mobile stations (MSs).
