Digital Pre-Distortion (DPD) is a technique to increase linearity or compensate for non-linearity in power amplifiers. ... Digital Pre-Distortion applies inverse distortion, using a pre-distorter, at the input signal of the PA to cancel the distortion generated by the power amplifier.
What is DPD and CFR?
Abstract: Digital predistortion (DPD) and Crest Factor Reduction (CFR) are applied separately in radio frequency power amplifiers (PAs) in general. ... The combined CFR/DPD module ensures that the PAPR at the output of predistorter will not exceed a given limit.
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.
