Abstract
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.
