摘要： A method, circuit, and a system for performing digital predistortion are disclosed. Digital predistortion may be used to compensate for or null the distortion caused by power amplifiers. The distortion of power amplifiers is usually larger at higher magnitudes or powers, and therefore, a larger percentage of the samples collected for the digital predistortion may be of higher magnitude or power. At least one sample of lower magnitude or power may be ignored or not collected. Accordingly, fewer samples can be used to perform digital predistortion, thereby allowing digital predistortion to be performed more quickly and efficiently with fewer resources.
