摘要
In a method for an optimised transmission of data in a wired multi-carrier (multi-carrier modulation—MCM) transmission system from a transmitter to one or more receivers via a transmission channel, only one specified supply power is provided for the transmitter, a transmitted signal for transmitting data has a plurality of subcarriers, and the data together with redundant information is distributed to the plurality of subcarriers in such a way that the receiver can dispense with some of the subcarriers in order to determine the data. The method includes a step of determining frequency-dependent access impedances of the wired transmission channel on the transmitter, and a step of adjusting the signal amplitude of the individual subcarriers on the basis of the measured frequency-dependent access impedances sand the limited supply power.
