A device for processing a digital data signal in a CDMA radio transmitter includes a channelization device, a spectral shaping device and a frequency correction device. The channelization device adds a channel-individual CDMA code to the digital data signal, the spectral shaping device subjects the digital, channel-individualized data signal to a spectral shaping and the frequency correction device performs a spectral shift of the digital, spectrally shaped data signal.
