<p>The device has a pre-inverse block (21) receiving a complex time-slotted input signal and restoring a complex predistorted signal in an inlet of a power amplifier (10). The block has a function table module (211) associated with a complex time-slotted input signal modulus value contained in a segment. The module has a preset clearance of parameters defining a parametric model implemented in a parametric model module (212) of the block via a function. The latter module returns a value, where the complex predistorted signal is obtained from multiplication of the input signal by the value.</p>
