Digital representations of the real world are being used in many applications, such as augmented reality. 6G systems will not only support use cases that rely on virtual worlds but also benefit from their rich contextual information to improve performance and reduce communication overhead. This paper focuses on the simulation of 6G systems that rel...

Traffic demand in wireless communication systems has emerged as a key issue over recent decades. An ever-increasing trend is projected for the next few years, with explosive data traffic expected to materialize and mobile users imposing new quality of service requirements. This growing traffic demand, combined with increasingly complex heterogeneou...

O eletrocardiograma (ECG) avalia a atividade elétrica do coração, e pode ser utilizado para avaliar se a atividade cardíaca está dentro da normalidade ou se há alterações nos músculos e nervos do coração. O ECG consiste na gravação do sinal elétrico gerado pela atividade cardíaca, no entanto quando esse sinal é gravado está sujeito a diversas inter...

G.fast is one of the most recent DSL system standardized by ITU. It aims to achieve transmission rates of the order of Gbps over short loops, using bandwidth of 106 MHz or 212 MHz. Owing to its large bandwidth, the G.fast is susceptible to interference from a wide range of sources, one of the most damaging being alien crosstalk. This study provides...
Conference Paper
Full-text available
Phantom mode has been proposed to improve G.fast applications. However, the most of the phantom mode systems deploy the first phantom layer only. Nevertheless, this work analyses the feasibility of a system, which deploys an additional phantom mode level, called second phantom layer. The entire system, first and second layers and differential modes...
Article
Alien crosstalk is one of the major impairments for copper-based transmissions. This letter outlines a method for mitigating alien crosstalk for DSL downstream transmissions impaired by multiple interference sources. The method requires a reference channel, and includes a post processing stage in which induced correlation is applied to prepare the...
Conference Paper
Full-text available
The DSL technologies are expected to face many interferences in conventional deployments, such as RFI. One way to mitigate the destructive effects of RFI is to use the correlation between the RFI observed in differential mode and the RFI observed in common mode. This strategy is considered in many works found in the literature. However, they do not...
Conference Paper
G.fast is the most recent ITU-T standard for copper-based transmission, which targets at short distances and adopts a bandwidth of 106 MHz extensible to 212 MHz. In several scenarios G.fast systems will be composed by or coexist with uncoordinated lines, which are sources of strong crosstalk. This work focuses on evaluating an alien (out-of-domain)...
Conference Paper

This paper addresses the use of full reference metrics in the characterization of perceptual difference in a pair of images, in which one of them is degraded by additive white Gaussian noise (AWGN). Conventional (SNR, PSNR, and CC) and perceptual (MSSIM, IFC, VIF, and C4) full reference metrics are considered. The subjective experiment, which uphol...

O presente projeto pretende avaliar as características do AXT que impactam na correlação espacial da interferência observada no grupo vetorizado e que limitam o desempenho alcançado pelos métodos de mitigação de AXT baseados em predição em situações com transmissão G.fast. Especial atenção é dada a ambos o comportamento a respeito do número de fontes de AXT e ao desbalanceamento resultante dos métodos de mitigação. Este projeto também estenderá o trabalho apresentado em (Gomes et al 2015), motivado pela importância de AXT devido seu impacto em sistemas G.fast.
