digital predistortion

Definitions

A technique used to increase linearity or compensate for nonlinearity in power amplifiers.

countable, uncountable

Examples

“The result⟳ will be the enhancement of the RF performance by means of digital signal processing techniques such as digital predistortion for PA linearization [179, 180], improved DC-offset compensation for zero-IF receivers, or the above described on-chip calibration of an image-reject receiver [162] (section 8.3.3).”

“However, the extra cost⟳ arising from couplers and other components makes such techniques much more expensive than the digital predistortion technique.”

“Additional digital predistortions can further improve⟳ the PA linearity, and our PA’s built-in reconfigurability naturally augments such predistortions and potentially reduces their complexities.”
