Abstract This work presents an adaptive hybrid signal precoding strategy for Cell-Free (CF) Massive multiple-input multiple-output (MIMO) systems. The proposed solution exploits the advantages of both distributed and centralized signal processing sch

The 5G mobile communication systems introduce multiples functional splits between base station elements, new transmission bands and a large number of antennas supporting beamforming. In this scenario, a viable strategy to avoid building penetration l

A coleta de resíduos sólidos no município de Cametá carece de eficiência. Um dos principais fatores é a falta de planejamento por parte da prefeitura municipal que não está construindo políticas públicas eficientes. Nesse sentido, este trab

In this paper, we present an investigation about the potential of coaxial networks for 5G fronthaul. The study is motivated since some countries have a big coaxial infrastructure that could potentially be used for 5G applications. In this context, we

Accurate parametric models capable of describing the electrical characteristics of short twisted-pair cables operating at relatively high frequencies are key elements for design the next generation broadband over copper. In this paper we present an e

G.fast is a new standard from the International Telecommunication Union, which targets 1 Gb/s over short copper loops using frequencies up to 212 MHz. This new technology requires accurate parametric cable models for simulation, design, and performan

Digital subscriber lines (DSL), the broadband data transmission technologies that use the copper cable as channel, are the most used Internet media around the world with more than 300 million users (Oksman et al., 2010), Much of the DSL success is re

Recently, the industry and the academy started to discuss the development of the fourth generation DSL systems. For example, within this context, ITU started working in G. fast DSL standard. A trend in this new generation is to increase the end-user

This paper evaluates the capacity of MIMO DSL systems up to 100 MHz using short loops (50 and 200 meters) based on measured channel data. The experimental results show that these systems have capacities as high as 0.77 Gbps for the 50 m loop, for exa
