Special Issue Information

Dear Colleagues,

MIMO (multiple-input and multiple-output) systems are vital for technology in mobile communications, which increase spectrum efficiency and data rates. Spatial multiplexing of signals, one of the most significant features of MIMO systems, can provide higher reliability of wireless links and can be exploited to serve more users than any previous mobile communication technology. MIMO is adopted in almost every wireless network, such as Wi-Fi, 4G and 5G, and IoT, and will provide the basis for next generation (i.e., beyond 5G) networks.

The aim of this Special Issue is to present the current research on design and implementation of MIMO systems, with a perspective view on future trends for 6G communications. Topics of the submitted papers may include but are not limited to: MIMO antenna array design and characterization; radio wave propagation; multiuser and massive MIMO systems; energy efficiency; small cells and heterogeneous cells; applications of mm wave and sub-THz frequencies; MIMO for IoT and emerging technologies; application of artificial intelligence and machine learning to MIMO systems; measurements on modern Wi-Fi networks and systems; cognitive radio systems; measurement and assessment of electromagnetic field exposure generated by MIMO; 5G signals measurement methodologies; power monitoring and control systems for base stations; cell-free distributed MIMO; and beyond 5G communication systems, toward 6G.

Hybrid Beamforming in Massive MIMO for Next-Generation Communication Technology

by Shahid Hamid, Shakti Raj Chopra, Akhil Gupta, Sudeep Tanwar, Bogdan Cristian Florea, Dragos Daniel Taralunga, Osama Alfarraj and Ahmed M. Shehata

Abstract

Hybrid beamforming is a viable method for lowering the complexity and expense of massive multiple-input multiple-output systems while achieving high data rates on track with digital beamforming. To this end, the purpose of the research reported in this paper is to assess the effectiveness of the three architectural beamforming techniques (Analog, Digital, and Hybrid beamforming) in massive multiple-input multiple-output systems, especially hybrid beamforming. In hybrid beamforming, the antennas are connected to a single radio frequency chain, unlike digital beamforming, where each antenna has a separate radio frequency chain. The beam formation toward a particular angle depends on the channel state information. Further, massive multiple-input multiple-output is discussed in detail along with the performance parameters like bit error rate, signal-to-noise ratio, achievable sum rate, power consumption in massive multiple-input multiple-output, and energy efficiency. Finally, a comparison has been established between the three beamforming techniques. Full article

Joint User Clustering and Graph Coloring Based Pilot Assignment for Cell-Free Massive MIMO Systems

by Xinyu Huang, Yubo Wang, Shiyong Chen, Yan Li and Yucheng Wu

Abstract

Pilot contamination due to pilot reuse seriously mitigates the performance of the cell-free massive multiple-input multiple-output (MIMO) systems. In this paper, we propose a joint pilot assignment scheme that employs user clustering and graph coloring (UC-GC) to reduce pilot contamination. The proposed method consists of two steps: firstly, we utilize AP selection to classify all users; secondly, we assign pilots to users with more severe pilot contamination using the graph coloring algorithm and then assign pilots to the remaining users. The numerical simulation results show that the proposed scheme outperforms existing pilot assignment schemes and significantly improves throughout with low complexity. Full article

Abstract

At the dawn of the next-generation wireless systems and networks, massive multiple-input multiple-output (MIMO) in combination with leading-edge technologies, methodologies, and architectures are poised to be a cornerstone technology. Capitalizing on its successful integration and scalability within 5G and beyond, massive MIMO has proven its merits and adaptability. Notably, a series of evolutionary advancements and revolutionary trends have begun to materialize in recent years, envisioned to redefine the landscape of future 6G wireless systems and networks. In particular, the capabilities and performance of future massive MIMO systems will be amplified through the incorporation of cutting-edge technologies, structures, and strategies. These include intelligent omni-surfaces (IOSs)/intelligent reflecting surfaces (IRSs), artificial intelligence (AI), Terahertz (THz) communications, and cell-free architectures. In addition, an array of diverse applications built on the foundation of massive MIMO will continue to proliferate and thrive. These encompass wireless localization and sensing, vehicular communications, non-terrestrial communications, remote sensing, and inter-planetary communications, among others. Full article
