Abstract
A system and method for multi-band digital pre-distortion (DPD) for a non-linear system. The system includes a DPD circuitry configured to perform multi-band DPD on a multi-band input signal to compensate for a non-linearity of a non-linear system. The multi-band input signal includes input signals of multiple frequency bands and the DPD circuitry is configured to perform DPD on an input signal of each frequency band per frequency band. The DPD circuitry is configured to perform the DPD using a combination of a look-up table (LUT) that evaluates a non-linear function and computation of terms of a non-linear polynomial of one or more variables representing the input signals of multiple frequency bands. Both the non-linear function and the non-linear polynomial are in a reduced dimension lower than a dimension of the multi-band input signal.
