摘要：
A method is described for performing a linearization and an image-suppression algorithm in a broadband multi-band transmitter chain (10) that comprises a broadband feedback-path (33, 34, 24) providing a broadband feedback signal, wherein said method is characterized in that said linearization and image-suppression algorithms periodically are fed with said feedback signal for the duration of individual discrete time windows, in order to provide both algorithms with individual parts of said feedback signal that are free of linearization and/or image non-conformances due to time delay of said non-conformances within said feedback signal.
Furthermore a transmitter chain (10) to be used to execute the method mentioned above, plus a base station comprising such a transmitter chain (10) is described.
