Digital pre-distortion (DPD) adaptation flow and accompanying interfaces implemented in a programmable processing array

A wireless device, comprising:

• a memory configured to (i) store output data samples identified with a first data transmission, and (ii) store feedback data samples obtained via a feedback measurement that is performed with respect to the first data transmission;
• and
• a programmable processing array configured to compute adapted digital pre-distortion (DPD) parameters using (i) the output data samples, and (ii) the feedback data samples;
• and
• a hardware accelerator configured to apply, to transmit (TX) data samples identified with a second data transmission, DPD terms in accordance with the adapted DPD parameters,
• wherein the output data samples and the feedback data samples are provided to the programmable processing array in a time-aligned manner based upon a base station frame number (BFN) counter.
