DPK is short for digital pre-distortion calibration. It can adjusts digital waveform according to PA linear characteristics dynamically to enhance TX EVM. Do this calibration when we are going to run on AP channel. To prevent power offset out of boundary, it monitors thermal and set proper boundary to register.
