Embodiment Construction

[0032] In the following description of several advantageous exemplary embodiments of the invention, the same or similar reference symbols are used for elements that are shown in different figures and have a similar effect, wherein a repeated description of these elements is avoided.

[0033] figure 1 A block diagram of a device 100 for processing a radio signal 105 according to an exemplary embodiment of the invention is shown. The radio signal 105 is here received by one of the plurality of antennas 110 , which is selected as the receiving antenna by a corresponding antenna selection switch 115 . The radio signal 105 received by the corresponding antenna 110 is subsequently tuned into an HF (HF: High Frequency) processing unit 120 for HF processing, for example aliasing with a corresponding carrier frequency to obtain an intermediate frequency signal or a baseband signal. The signal 125 obtained in the RF processing unit 120 is digitized in an A / D converter, wherein the proc...

Abstract

The invention relates to a method (700) for processing radio signals (105). The method (700) includes the step of reading (710) of a data block (155), the data block having multiple data values (145) each of which corresponds to one value of radio signals (105) sampled during a preset limited period of time. Moreover, the method (700) includes the step of analyzing (720) the multiple data values (145) of the data block (155) to determine processing parameters (225). The method (700) further includes the step of demodulating (730) each data value (145) of the data block (155) by means of processing rules (235, 410, 420) associated with the processing parameters (225) to process the radio signals (105).

Description

technical field [0001] The invention relates to a method for processing radio signals, to a corresponding device and to a corresponding computer program. Background technique [0002] Radio receivers based on digital signal processing for modulation types AM or FM are now implemented "sampling-based". This means that a signal processing process will start every time a new sample value arrives. The arrival of the new value and the execution of the processing step will be carried out synchronously. If the reception control software, for example, implements a frequency detuning of the high-frequency part of the receiver, the effect will be immediately available (eg signal field strength changes). Furthermore, measures to improve the reception quality cannot be implemented retroactively. [0003] Signal processing for analog modulation standards such as AM and FM and signal processing for digital modulation standards such as DAB or DRM cannot be carried out in parallel on the...
