Abstract
A signal processing circuit arrangement may include a preamplifier circuit configured to map a first dimension input and a second dimension input to a first subset of a plurality of lookup table coefficients of a two-dimensional (2D) lookup table, wherein the first dimension input and the second dimension input each represent a signal level of one or more input signals, extrapolate from the first subset of the plurality of lookup table coefficients to generate a lookup table output, and apply the lookup table output to the one or more input signals to generate a predistorted input signal for an amplifier.
