Abstract
Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive an indication that the UE is to apply a digital-post distortion (DPoD) procedure to a received signal to reduce non-linearities of the received signal. In some examples, the UE may determine one or more autocorrelation values for a power delay profile (PDP) of a channel, receive an indication of a matrix, and identify coefficients (e.g., b-coefficients) for use in the DPoD procedure based on multiplying the autocorrelation values and the matrix. Alternatively, a network entity may determine the autocorrelation values indicate them to the UE for use in identifying the coefficients. In some other cases, the network entity may use the autocorrelation values and the matrix to determine the coefficients and then may indicate the coefficients to the UE. The UE may apply the DPoD procedure to the received signal using the coefficients.
