PROBLEM TO BE SOLVED: To provide a method for joint reduction of NEXT and FEXT crosstalks related to a time division duplexed DSL system. SOLUTION: A NEXT interference is successively removed, and a FEXT interference from a receiver DSL signal following it is removed. Crosstalk is removed from the principal signal in a synchronized TDD DSL system having at least one NEXT generating channel and at least one FEXT generating channel that generate NEXT interference and FEXT interference in the principal signal, respectively. Signal data, which includes received signal data for the principal channel and the FEXT generating channel, transmitted signal data for the NEXT generating channel, channel transfer function data and crosstalk coupling coefficient data for the principal channel, each NEXT and each FEXT generating channel, is acquired. After the signal data is acquired, the NEXT interference is removed. And then VDMT FEXT is removed, and the FEXT interference is removed. COPYRIGHT: (C)2003,JPO
