Abstract

In one embodiment of the present invention, a weight vector is generated based on a pre-distorted input signal and an output signal of an amplifier using a computation reduction technique. The computation reduction technique decomposes a number of multiplication operations between complex numbers such that a number of multiplications and a number of additions to generate the weight vector is reduced as compared to if the number of multiplication operations between complex numbers was not decomposed. An input signal for input to an amplifier is pre-distorted based on the generated weight vector.
