Abstract

Method for transmitting an analog data stream with sampling rate increase in the data stream transmitter, and a circuit arrangement for carrying out the method The invention provides a method for transmitting an analog data stream (101), which is composed of discrete multitone symbols (208), from a data stream transmitter (214) via a transmission channel (102) to a data stream receiver (215), interpolation between successive samples of a supplied multitone signal (303) being carried out in an interpolation device (109) of the data stream transmitter (214), amd coded data blocks (125) which are generated by means of a coding device (202) from data (123) to be transmitted being inversely transformed from the frequency domain into the time domain in conjunction with a number of carriers, increased by comparison with an ADSL Standard, in an inverse transformation device (203) of the data stream transmitter (214).
