Patent abstract
A method of transmit power adjustment in multitone communication systems is performed by changing a power spectral density for each subchannel k the power spectral density to the minimum of the power spectral density and a miximum of the power spectral density REFPSD(k)=min(NOMPSD(k), NOMPSD−PCB) where REFPSD(k) is the transmitted PSD at tone k, NOMPSD(k) is the maximum transmit PSD allowed at each tone k, NOMPSD is the maximum value of NOMPSD(k) over all k and PCB is a power cutback level.
