Digital Pre-Distortion (DPD) is a technique to increase linearity or compensate for non-linearity in power amplifiers. Power amplifiers are critical in communication systems and it is crucial to improve their efficiency and overall performance.

What is DPD algorithm?

Digital predistortion (DPD) is a baseband signal processing technique that corrects for impairments in RF power amplifiers (PAs). These impairments cause out-of-band emissions or spectral regrowth and in-band distortion, which correlate with an increased bit error rate (BER).

What is DPD in WIFI?

The PA and Digital Pre-Distortion (DPD)

The PA is the most critical component of the RF radio in a Wi-Fi transmitter. ... DPD uses software models to measure the nonlinearity of the PA and create an inverse signal using a software-enabled pre-distortion algorithm, which then linearizes the PA output signal.
