Full vectoring optimal power allocation in xDSL channels under per-modem power constraints and spectral mask constraints
In xDSL systems, crosstalk can be separated into two categories, namely in-domain crosstalk and out-of-domain crosstalk. Indomain crosstalk is also refered to as self crosstalk. Ou...
