1. A method for wireless communications at a network entity, comprising:
performing a signal processing procedure on an input signal to generate an output signal, performing the signal processing procedure comprising:
performing a digital pre-distortion process on the input signal according to a set of digital pre-distortion coefficients to compensate for a distortion of a power amplifier; and
performing a crest factor reduction process on the input signal subsequent to performing the digital pre-distortion process, wherein the set of digital pre-distortion coefficients are based at least in part on performance of the crest factor reduction process;
amplifying the output signal via the power amplifier to generate an amplified signal; and
transmitting, to a user equipment (UE), the amplified signal via one or more antennas.
