Abstract: A method for the wireless transmission of data between at least one communication unit (2) which is arranged in or on a rotatable part (1) and to which at least one sensor (S) and/or actuator is respectively connected, and at least one base communication unit (4) which is arranged in radio reception range outside of the rotatable part is described. Transmission of the data using the ultrawideband radio transmission method (UWB) on a frequency spectrum of more than 500 MHz or a frequency bandwidth of more than 0.2 times the average transmission frequency is proposed.

Abstract: A method is provided for the decoding of digital audio data, which is used to perform an error recognition dependent on transmitted reference values, e.g., scale factors. The method includes the comparison of reference values of a subband with preceding reference values of the same subband, in order to produce a characteristic that is compared with a threshold value, and that, if the characteristic is located above the predetermined threshold value, this is indicated by a signaling. In an example embodiment of the present invention, it is provided that in subbands in which no audio data are transmitted a default value is entered, which leads to the result that no characteristic is produced for this subband.

Abstract: A method for overriding interference in a reproduced audio signal which is derived from a digital signal, the reproduced audio signal being attenuated as a function of data error statistics of the digital signal, which is distinguished by the fact that a substitute signal is superimposed on the attenuated audio signal as a function of the data error statistics of the digital signal. The method advantageously ensures that, even in the case of very noisy digital input signals, a signal is acoustically reproduced at any time, so that the volume set on an appropriately equipped radio receiver is able to be anticipated realistically for the user at any time. This avoids deceiving the user about the volume of the reproduction that is actually set, which in the case of a very noisy received signal, as a result of the interruption of an audio reproduction, is no longer determinable according to the related art.

Abstract: A method of decoding digital audio data is described; it is used to implement error concealment as a function of an error count in which the preceding data is also taken into account. Therefore, equalizer values, through which dequantization of the received digital audio data is implemented, are determined. The equalizer values are either stored or computed. If the error count is greater than a predetermined highest threshold value, a muting is activated. If the error count is less than the lowest predetermined threshold value, no equalizer values are used for dequantization.
