Real-time FEXT Crosstalk Identification in ADSL Systems

The IEEE International Symposium on Intelligent Signal Processing - WISP 2003, Budapest, Hungary, 4-6 September 2003.

Abstract: FEXT crosstalk identification results to improved frequency spectrum utilization in ADSL systems. The accurate determination of the crosstalk transfer function is a demanding task that is affected by various system impairments. In this paper we investigate the performance of a real-time method that exploits the exchange of signaling information of a new activated ADSL line in order to determine the crosstalk function between this line and an existing operational line.
