Whiting, P.A. (author), Kramer, G. (author), Nuzman, C.J. (author), Ashikhmin, A. (author), van Wijngaarden, A.J. (author), Živković, M. (author)Digital subscriber line (DSL) data rates for short loops are typically limited by crosstalk between adjacent lines rather than by background noise. Precoding can reduce crosstalk in the downstream from the access node to the customer premises equipment significantly if an accurate estimate of the inverse crosstalk channel is provided. Recently,...article 2011

van den Berg, D. (author), Barink, M. (author), Giesen, P. (author), Meinders, E.R. (author), Yakimets, I. (author), TNO Industrie en Techniek (author)Thin polymer substrates are promising materials for flexible electronics with many advantages. However, the dimensional stability of polymer substrates is low. Nowadays, this is overcome by laminating polymer substrates onto a rigid carrier. Nevertheless, carrier-less processing will be a foreseen next step for future manufacturing of plastic...article 2010
