Abstract:
Embodiments for methods and apparatuses for processing a multi-carrier signal are disclosed. One method includes shaping a frequency spectrum of a multi-carrier transmit signal wherein an amplitude of a plurality of subcarriers of the multi-carrier transmit signal is increased relative to at least one other subcarrier of the multi-carrier transmit signal. The shaped frequency spectrum multi-carrier transmit signal is amplified with a power amplifier, wherein a power level of an output of the power amplifier is greater than a rated power level of the power amplifier.
