1. A user equipment (UE) for wireless communication, comprising:
one or more memories storing processor-executable code; and
one or more processors coupled with the one or more memories and individually or collectively operable to execute the code to cause the UE to:
receive, from a network entity, an indication that the UE is to apply a digital post distortion procedure to a received signal for reducing a transmitter-introduced non-linearity component of the received signal;
determine one or more autocorrelation values for a power delay profile of a communication channel associated with the received signal;
identify a plurality of coefficients for use in the digital post distortion procedure, wherein the plurality of coefficients are based at least in part on the one or more autocorrelation values; and
apply the digital post distortion procedure to the received signal by using the plurality of coefficients.
