Abstract:
1. Method for transmitting an analog data stream from a data stream transmitter to a data stream receiver by means of discrete multitone symbols, in which: a) inputting data to be transmitted into a data input device of the data stream transmitter; b) coding the data to be transmitted in a coding device and combining the data to be transmitted into coded data blocks; c) transforming the coded data blocks into a multitone signal in an inverse transformation device; d) converting the multitone signal into an analog transmitter signal in a digital-to-analog converter; and e) transmitting the analog transmitter signal via a transmission channel, wherein transient processes are provided by means of redundant compensation signals in the data stream transmitter, so that the crest factor of modulated signals of the analog data stream is reduced, and wherein transient processes are predetermined in the data stream transmitter by stores of at least one filtering device provided in the data stream transmitter being preloaded with predeterminable storage values, wherein storage contents of the at least one filtering device provided in the data stream transmitter decay in accordance with recursive components of the filtering device such that the redundant compensation signals are generated.
