Frequency domain crosstalk canceling between VDSL2 systems with different symbol rates

ITU-T recently published recommendation G.993.5 for frequency-domain crosstalk cancellation, to be used in conjunction with VDSL2. This standard assumes identical symbol rates for all systems. After a brief review of G.993.5, we discuss an extension of frequency-domain crosstalk cancellation to cover the different symbol rates specified for VDSL2.
