Claim Text:
1. An apparatus of a device for wireless communication, the apparatus comprising: predistortion circuitry to pre-distort digital baseband samples for a plurality of component carriers and generate a predistorted baseband signal for each component carrier, the predistortion circuitry to perform amplitude correction based on a roll-off characteristic associated with the component carriers; combiner circuitry to generate a digital multicarrier signal from the predistorted baseband signals; group-delay (GD) predistortion circuitry to provide an inverse group delay characteristic to the multicarrier signal; crest-factor reduction (CFR) circuitry to reduce a crest factor of the multicarrier signal after operation of the GD predistortion circuitry; and transceiver circuitry to generate an orthogonal frequency division multiplexed (OFDM) signal, from the multicarrier signal, for each component carrier, for transmission, after CFR.
