METHOD AND SYSTEM FOR THE ENERGY-OPTIMIZED TRANSMISSION OF DATA IN A WIRED MULTICARRIER MODULATION (MCM) TRANSMISSION SYSTEM

摘要

The invention relates to a method and a system for the optimized transmission of data in a wired multicarrier modulation (MCM) transmission system. The method for an optimized transmission of data in a wired multicarrier modulation (MCM) transmission system from a transmitter to one or more receivers via a transmission channel, wherein 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 such that the receiver can dispense with some of the subcarriers in order to determine the data, has the following steps: • determining frequency-dependent input impedances of the wired transmission channel to the transmitter, and • adjusting the signal amplitude of the individual subcarriers on the basis of the measured frequency-dependent input impedances and the specified supply power.
