Dissertação (Mestrado em Engenharia Elétrica) - Instituto de Tecnologia, Universidade Federal do Pará, Belém, 2009. Disponível em: http://repositorio.ufpa.br/jspui/handle/2011/3440. Acesso em:.https://repositorio.ufpa.br/handle/2011/3440The current work presents tests and laboratory experiments to measure crosstalk and impulsive noise in DSL systems, which are of great importance for the improvement and development of this technology. The crosstalk study was focused in a measurements campaign of short-length cables operating at extremely high frequencies. The results were used in the transmission rates calculation of DSL systems operating in this type of unexplored scenario. The impulsive noise study focused on the development of a telephone line digitizing system allowing real measurements of the noise.porAcesso AbertoLinhas digitais de assinantesCrosstalkRede DSLRuído (Telecom)DissertaçãoCNPQ::ENGENHARIAS::ENGENHARIA ELETRICA::TELECOMUNICACOESCNPQ::CIENCIAS EXATAS E DA TERRA::CIENCIA DA COMPUTACAO::SISTEMAS DE COMPUTACAO::ARQUITETURA DE SISTEMAS DE COMPUTACAO
