Method for compensating for peak values during a data transmission with discrete multitone symbols and a circuit arrangement for carrying out the method

An apparatus for generating an analog transmitter signal (211) in order to transmit an analog data stream (101) from a data stream transmitter (214) to a data stream receiver (215) by means of discrete multitone symbols (208), having:

• a) a data input device (201) provided in the data stream transmitter (214) and serving for inputting data (123) to be transmitted;
• b) a coding device (202) for coding the data (123) to be transmitted into coded data blocks (125);
• c) an inverse transformation device (203) for transforming the coded data blocks (125) into a multitone signal (303);
• and
• d) a digital-to-analog converter (204) for converting the multitone signal (303) into the analog transmitter signal (211),
• characterized
• in that the data stream transmitter (214) has at least one filtering device (131, 132, 133), which provides transient processes by means of redundant compensation signals in order to reduce the crest factor of modulated signals of the analog data stream (101).
