Abstract:
1. A method for transmitting an analog data stream, the method having the following steps: a) receiving the analog data stream via a transmission channel in a data stream receiver; b) converting the received analog data stream into a digital data stream by sampling the analog data stream with a sampling rate in an analog/digital converter; c) decimating the digital data stream in a decimation device in order to provide a decimated digital data stream; d) deriving a control signal from either the digital data stream or the decimated digital data stream according to a predeterminable adjustment of a switching device; e) supplying the derived control signal to a coefficient determining device; f) supplying a reference signal, input via a reference signal input device, to the coefficient determining device; g) determining at least one coefficient of an equalizer by means of the coefficient determining device in dependence on the reference signal supplied and in dependence on the control signal supplied; h) equalizing the decimated digital data stream in the time domain in the equalizer to which at least one determined coefficient has been applied, in order to provide an equalized decimated digital data stream; i) transforming the decimated equalized digital data stream from the time domain into the frequency domain by means of a transformation device, in order to provide transformation signals which are defined in amount and phase; j) correcting the transformation signals in a correction device in order to provide corrected transformation signals; k) determining at least one amount signal and at least one phase signal from at least one corrected transformation signal in a determining device; l) decoding the at least one amount signal determined in the determining device and the at least one phase signal in a decoding device in order to provide a decoded data stream; and m) outputting the decoded data stream via a data output device.
