Abstract:
1. A multiple-input-multiple-output, MIMO, communication device comprising: a link controller configured to assign transmit power to two or more transmission channels, each of said transmission channels having preassigned a portion of transmit power for each of a group of subcarriers, said link controller being further configured to reassign, for each subcarrier of said group of subcarriers and on the basis of information contained in tonemaps for each transmission channel, all of the preassigned transmit power portion of a transmission channel that is not used for transmitting information at a respective one of the subcarriers, to only the same respective subcarrier on one or more other transmission channels that are used for transmitting information such that respective subcarriers having been reassigned transmit power have more transmit power than respective subcarriers on the one or more transmission channels not used for transmitting information, wherein the respective subcarriers having been reassigned transmit power have a transmit power which is the sum of the preassigned transmit power and the reassigned transmit power.
