Intermittent transmission through low power states and discontinuous operation has been
introduced in G. fast to enhance energy efficiency. In combination with vectoring, crosstalk …

Precoding is a technique that counteracts the crosstalk in downlink digital subscriber line
(DSL) transmission. While linear precoding is adequate in the VDSL2 technology because …

Today, accurate and low complexity modelling of secondary parameters of twisted copper
pairs at high frequencies is necessary, especially for modern transmission systems. The …

Recently, a new xDSL successor called G. fast, which can occupy frequencies up to 106 or
212~ MHz, has been introduced in ITU-T G. 9700 series of recommendations. Moreover, a …

A trend for the 5th generation fixed broadband access networks is to provide data rates as
high as 10 Gbps to the subscribers. Since fiber-to-the-home (FTTH) connectivity is still …

In this dissertation, we study the effect of error protection strategies and precoding
techniques on the error performance and quality of service of the end application. We …

As the higher and higher frequency bands of existing metallic cables in access networks are
being continuously exploited by modern transmission technologies, such as the G. fast, the …

Metallic cables are still frequently used in access telecommunications networks, especially
in the last-mile network segments, together with digital subscriber line (DSL) technologies …

G. fast is a new standard for fixed broadband access that aims at achieving bit rates of 1
Gb/s over short copper loops. In order to give support to simulation, design and performance …

As redes de acesso usando cabos de cobre atualmente utilizam bandas de frequência até
30 MHz, especificada no padrão VDSL2. À medida que arquiteturas híbridas de fibra e …
