Evaluation of DSM Performance with Mixed DSL Services and Measured Crosstalk Channels

Year: 2007

Type: conference-paper

Abstract: In most works published so far, dynamic spectrum management (DSM) techniques are simulated assuming a single service (e.g.ADSL) and classical copper-pair channel models described in standards for spectrum management.This work presents an evaluation of DSM algorithms based on measured channels and with multiple services.A measurement campaign was performed to completely characterize scenarios by measuring the direct and far-end crosstalk transfer functions.Results for a total of two scenarios of ten twisted pairs (200 measurements), involving both equal and non-equal length cables are presented.The work also presents a thorough investigation of state-ofart DSM algorithms (namely, ISB, ASB, SCALE and IWF) simulated in multiple services (namely, ADSL, ADSL2+ and VDSL2) scenarios.
