Abstract
An active antenna array for a mobile communications network comprising: a digital signal processor connected to a plurality of digital-to-analogue conversion blocks; a plurality of antenna elements; a plurality of transmission paths, whereby an individual one of the plurality of transmission paths is connected between an individual one of the digital-to-analogue conversion blocks and an individual one of the plurality of antenna elements, whereby an individual one of the plurality of transmission paths comprises a predistorter and a coupler; a plurality of paths connected between an individual one of the couplers and a single combiner; a single feedback path connected between the single combiner and a predistorter coefficient calculation unit; and a coefficient update path connected between the predistorter coefficient calculation unit and at least an individual one of the predistorters.A method for predistortion of radio signals is also disclosed.
