摘要： The invention relates to a device for predistorting a transmission signal (S1) to be transmitted via a nonlinear transmission path (10), comprising an estimation device (14, 16) for detecting an error signal (S2') depending on the transmission signal (S1) and a previously detected transmission characteristic of the nonlinear transmission path (10). The error signal (S2') represents an estimation of the error generated by nonlinearity of the transmission path (10). A time-dispersive element (18) is provided in order to produce a correction signal (S3) by temporal extension of the error signal (S2'). A combiner (20) is provided in order to combine the transmission signal (S1) and the correction signal (S3). As a result of temporal extension of the error signal (S2'), an error signal fragment in the frequency spectrum of a transmission signal (S4) transmitted by the nonlinear transmission path (10) is displaced from the useful frequency range of the transmission signal.
