Verfahren zum Übertragen von digitalen Daten über störbehaftete Rundfunkkanäle und Vorrichtung zum Empfang von über störbehaftete Rundfunkkanäle übermittelten digitalen Daten

摘要

The invention concerns a process for transferring the digitally-coded data of a radio programme (A) in which the digitally-coded data are modulated according to a modulation process, in particular the OFDM modulation process. The data are modulated on at least one carrier wave and are transferred in a transfer frame. The process is characterized in that the data of a radio programme (A) are transferred such that they are repeated at least once and then evaluated together. In this way the complex values (20, 21) prepared by the demodulator circuit (53) are added. The invention further concerns a device for receiving the digitally-coded data of a radio programme (A) which device comprises, in addition to a high-frequency converter stage (51), an analog-to-digital converter (52) and a demodulator circuit (53), a buffer store (57) which temporarily stores at least the data of the time section of the radio programme (A) for the first transmission. The device finally comprises an adding stage (58) in which the data in the buffer store (57) are added to the corresponding data when the radio programme (A) is re-transmitted.
