Claim Text:
1. A method for adjusting sidelobes of signals transmitted from a plurality of antenna elements, the plurality of antenna elements being connected to a plurality of digital transceivers, whereby the plurality of digital transceivers receive transceiver signals for transmission to the plurality of antenna elements, the method comprising: detecting a requirement to adjust the sidelobes, said detecting comprising a detection of malfunction of at least one individual transceiver of the antenna array; adjusting weights of a plurality of transceiver signals feeding the antenna elements such that the sidelobes are adjusted and unacceptable deviations from the required radiated output power are compensated by tilt adjustments, wherein the unacceptable deviations comprises a coverage loss; using a feedback loop for measuring signal and/or data relative to an operation of an individual transceiver of the plurality of transceivers for providing a feedback signal, the feedback loop being configured to detect a functionality of said individual transceiver and being further configured to detect whether a non functional transceiver could become functional again; analyzing the feedback signal, and deciding how to modify complex value weights for transceiver signals of individual transceivers, based on information derived from the analyzed feedback signal.
