  • System and method for compensation of non-linear transmitter distortion
    Patent number: 7924956
    Abstract: A system, apparatus, method and article to provide compensation of non-linear transmitter distortion are described. The apparatus may include a receiver node (130) to receive information from a transmitter node (120). The receiver node (130) may include a clipping ratio estimation module (142) to determine parameters of non-linearity of a transmitter at the receiver node (130), a training signal predistortion block (150) to generate predistorted training symbols at the receiver node (130) using the parameters of non-linearity, and a channel equalization block (146) to performing linear equalization at the receiver node (130) using the predistorted training symbols. Other embodiments are described and claimed.

  • Multicarrier transmitter and methods for generating multicarrier communication signals with power amplifier predistortion and linearization
    Publication number: 20060067426
    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
    Publication number: 20060008028
    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.
