<p>The invention relates to a digital predistortion device (100) for applying a predistortion to a signal that is to be processed by a power amplifier (200), wherein said digital predistortion device (100) comprises at least two predistortion branches (111, 112), wherein each of said predistortion branches (111, 112) is configured to apply a predistortion to an input signal (S1, S2) of said predistortion branch (111, 112) according to a predistortion function (f_DPD1, f_DPD2) associated with said predistortion branch (111, 112), wherein a predistortion function (f_DPD1, f_DPD2) of at least one of said predistortion branches (111, 112) depends on the input signals (S1, S2) of at least two of said predistortion branches (111, 112).</p> |
