    摘要: A method for adjusting transmission parameters of a transmitter for digital radio signals, for example, broadcast signals, is described, in which context a receiving apparatus receives the digital radio signals emitted by the transmitter and transfers data to the transmitter via a return channel, transfer data and reception parameters being contained in the data. The transmitter then optimizes the transmission parameters as a function of these data. It is possible in this context that in the data, the transfer data either contain the received digital radio signals, or already have evaluation data from the receiving apparatus. The method is suitable in particular for digital radio signals that are transferred below 30 MHz. The return channel is operated either in simplex mode from the receiving apparatus to the transmitter, or in duplex mode.

    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).
