Modern life increasingly depends on faster Internet access for applications such as email, voice, information search, and a variety of social interconnections, while IPTV is increasing Internet video use. Growing wireless connectivity will substantially increase access bandwidth demand over the next decade. Figure 1 shows digital subscriber line (DSL)(More)
ADSL While high-bit-rate DSL (HDSL) was still in prototype phase, Stanford University and AT&T Bell Labs developed asymmetrical DSL (ADSL) technology from concept to prototype (1990-1992). Field technology trials began three years later and ANSI issued the first standard for ADSL in 1995 (T1 413 issue I); the second issue followed in 1998. The first ADSL(More)
The densification of mobile networks in order to meet increased capacity demands is ongoing, needed and costly. A few papers have been published based on the insight that the fixed broadband networks offer a multitude of sites, for instance our homes, for potential small cell deployment providing backhaul capacity and power without site costs. However, in(More)
Due to the much higher crosstalk impairing in high frequency channels compared to digital subscriber line (DSL) low frequency channels, the nonlinear TomlinsonHarashima precoding (THP) has a good potential to enhance the system performance. However, ordering plays an important role for the data rate performance in THP. The users precoded(More)
Radio-over-copper is a niche idea that has potential to become a cornerstone in the deployment of dense 5G networks. We address one of the remaining hurdles and present an architecture for transparent crosstalk mitigation in LTE-over-copper systems. By taking advantage of reference symbols present in the downlink LTE signals we propose two methods for(More)
