Abstract:
1. A method for pre-distorting an input for a device, comprising: acquiring a set of data pairs during a closed-loop calibration period of the device; searching the set of data pairs for at least one missing data pair; interpolating at least one interpolated data value for the at least one missing data pair; storing an augmented set of data pairs in a lookup table, wherein the augmented set of data pairs includes the set of data pairs and the at least one interpolated data value; and pre-distorting the device input during an open-loop operation period subsequent to the closed-loop calibration period of the device, wherein the pre-distortion is based on the augmented set of data pairs stored in the lookup table; wherein each of the data pairs comprises an original input value and a corresponding pre-distorted input value; wherein the interpolated data value is a pre-distorted input value y interpolating the interpolated data value according to an equation wherein x
