Joint Partial Crosstalk Cancellation and Spectrum Management for xDSL Systems with Data Rate Constraints

Monique Düngen
Abstract
xDSL systems have to be able to support an always increasing amount of high-rate applications. To make the applications run stably, service providers need to be capable of guaranteeing these high data rates to their customers at a limited amount of available computational complexity usable for crosstalk cancellation.
In order to be able to support high data rate targets with a low amount of computational complexity, partial crosstalk cancellation was combined with spectrum management techniques. A selection procedure was found, which jointly chooses the canceled crosstalkers and the transmit powers for each user on each tone by interlacing Iterative Water Filling (IWF) and a newly developed successive crosstalk selection algorithm for partial crosstalk cancellation, which takes into account the data rate requirements of the users. It distributes the available computational complexity in an intelligent way, so that data rate requirements are fulfilled. With the joint procedure savings in computational complexity are achieved.
