A linearization means for a component (eg an amplifier) in which the inverse transfer function for a predistorter is adjusted in dependence on the I/P and O/P

摘要

A method of linearising the output signal of a component e.g. power amplifier having an input signal comprising; taking an initial estimated representation of the pre-distortion inverse curve, manipulating said representation; pre-distorting said input signal by applying values of said representation to the input signal; determining the error in terms of linearity between the input signal and the output signal; and repeating previous steps such that the error is minimised.
