Patent ID: 6999738

Claim:
A device for pretreating a signal (S 1 ) to be transmitted over a transmission path, wherein the transmission path comprises a band-pass filter ( 14 ) whose pass-band width ( 30 ) is smaller than a predetermined bandwidth and a non-linear amplifier ( 16 ), comprising: linearization means ( 20 ) for performing such a linearization of the signal (S 1 ) to be transmitted before the transmission of the same, that a non-linearity caused by the non-linear amplifier ( 16 ) is counteracted; a signal shaping means ( 22 ) downstream to the linearization means ( 20 ) comprising such a frequency response ( 32 ) that the overall frequency response ( 34 ) of the signal-shaping means ( 22 ) and the band-pass filter ( 14 ) corresponds to the frequency response of a filter whose pass-band width is at least equal to the predetermined bandwidth wherein the linearizer and the signal-shaping means are arranged in the ground station of a satellite transmission system and wherein the band-pass filter and the non-linear amplifier are arranged in a satellite of the satellite transmission system.
