Data transmission method for transmitting an analog data stream from a stream transmitter to a stream receiver uses discrete multi-tone symbols converted as analog-digital signals

摘要

Data to be transmitted (123) is entered into a data input device (201) on a data stream transmitter and then encoded in an encoder (202). Preserved encoded data blocks (125) are transformed into a multi-tone signal in an inverse transformer (203). A digital-analog converter (204) changes the multi-tone signal into an analog transmitter signal (211) transmitted via a transmission channel (102). An Independent claim is also included for a device for generating an analog transmitter signal so as to transmit an analog data stream from a stream transmitter to a stream receiver by means of discrete multi-tone symbols.
