Linearization of a non-linear electronic device

A linearizer device for enabling linearization of a non-linear electronic device, the linearizer device comprising processing circuitry, the processing circuitry being configured to cause the linearizer device to:

• receive an input signal (x) destined to be input to the non-linear electronic device;
• wherein input-output characteristics of the non-linear electronic device is in the linearizer device represented by a linearization function defined by a LUT based model of base functions, and wherein the linearizer device is configured to in a greedy pursuit framework select the base functions according to a signal reconstruction criterion,
• obtain an output signal (y) by subjecting the input signal (x) to the linearization function;
• and
• provide the output signal (y), instead of the input signal (x), as input to the non-linear electronic device, thereby enabling linearization of the non-linear electronic device.
