  • Multicarrier transmitter and methods for generating multicarrier communication signals with power amplifier predistortion and linearization
    Patent number: 7463697
    Abstract: A multicarrier signal is generated by pre-compensating frequency-domain subcarrier symbols for substantially linear distortion subsequently introduced by a time-domain baseband filter.

  • Power amplifier linearization methods and apparatus using predistortion in the frequency domain
    Patent number: 7336716
    Abstract: To mitigate the effects of non-linear amplification in a digital transmission system employing a multi-carrier multiplexing communications technique, such as orthogonal frequency division multiplexing or discrete multi-tone, predistortion of an input signal to a power amplifier with a non-linear transfer characteristic is performed in the frequency domain by modifying frequency-domain symbols used to modulate individual sub-carriers. The frequency-domain symbols are modified in a manner that compensates for the amplifier's non-linear transfer characteristic.
