发明名称 METHOD FOR TRANSMITTING DIGITAL DATA VIA NOISE-ENCUMBERED RADIO CHANNELS AND DEVICE FOR RECEIVING DIGITAL DATA TRANSMITTED VIA NOISE-ENCUMBERED RADIO CHANNELS
摘要 A method for transmitting digitally coded data of a radio program (A) is proposed, in which the digitally coded data are modulated by a modulation method, in particular by OFDM. The data are modulated to at least one carrier wave. The data are transmitted in a transmission frame. The method is characterized in that the data of a radio program (A) are transmitted, with at least one repetition, and then are evaluated in common. In this process the complex values (20, 21), which have been furnished by the demodulator circuit (53), are added together. For a device for receiving digitally coded data of a radio program (A), it is proposed that in it, not only an high-frequency conversion stage (51), an analog/digital converter (52) and a demodulator circuit (53) but also a buffer memory (57) are provided, in which buffer memory at least the data of the time segment of the radio program (A) upon the initial transmission are buffer-stored, and finally an adder stage (58) is provided, in which the data in the buffer memory (57) are added to the corresponding data upon the repeat transmission of the radio program (A) (Fig. 5).
