Abstract

Waveforms may be shaped in a wireless communications device by processing head tones of a multi-tone carrier using a head tone waveform shaping characteristic to provide a first sub-symbol, processing tail tones of the multi-tone carrier using a tail tone waveform shaping characteristic to provide a second sub-symbol, and processing center tones of the multi-tone carrier using a center tone waveform shaping characteristic to provide a third sub-symbol. The first, second, and third waveform shaping characteristics may be different from each other, i.e., the waveform shaping may be asymmetric. The first, second, and third sub-symbols may be combined to provide an output symbol.
