Abstract
In this paper, a frequency selective NEXT cancellation algorithm for xDSL transmission is proposed. NEXT is cancelled by subtracting estimated noise from the received signal. An adaptive filter is used to estimate the band limited interference noise from the interference data. This algorithm is applied for a DSL application where asymmetric and symmetric services coexist. It showed about 40% improvement of transmission speed
