    摘要: The present invention relates to a method for estimating a first parameter (|H12(f)|, arg(H12(f))) that characterizes a first crosstalk channel (XCHDS12) from a first transmission medium (12b) towards a second transmission medium (12a) in a first direction of communication (DS).A method according to the invention further comprises the steps of: estimating a second alike parameter (|G21(f)|, arg(G21(f))) that similarly characterizes a second crosstalk channel (XCHUS21) from the second transmission medium towards the first transmission medium in a second opposite direction of communication (US) and at a first frequency index (f1), thereby yielding a first parameter value (|G21(f1)|, arg(G21(f1))), estimating the second parameter at a second distinct frequency index (f2), thereby yielding a second parameter value (|G21(f2)|, arg(G21(f2))), deriving a value (|H12(f3)|, arg(H12(f3))) for the first parameter at a third distinct frequency index (f3) from the first parameter value and the second parameter value. The present invention also relates to a crosstalk estimation unit, and to an access multiplexer or a network analyzer including such a crosstalk estimation unit.

    摘要: A network includes an access link and a local area link. The access link and the local area link are interferingly coupled. A method for performing spectrum management in view of a constraint in the network includes quantifying interference between the access link and the local area link, determining a first spectral configuration for a first transmitter operating over the access link, and determining a second spectral configuration for a second transmitter operating over the local area link. The determining of the first spectral configuration and the determining of the second spectral configuration are performed such that the respective achievable channel capacities of the access link and the local area link meet the constraint.
