Abstract (en)
[origin: WO2007014869A1] The invention relates to a radio-receiving device (1) provided with a receiving part (2) which comprises a mixer oscillator (VCO), whose oscillation frequency is coupled to the frequency and/or phase of a reference oscillator (20) and which is used for converting a radio reception signal (HF) on an intermediate frequency, and a signal processing part (3) which is placed downstream for processing the intermediate frequency signal (ZF) and comprises means (16, 16a, 16b) for determining a frequency deviation between the reference frequency (RF) of the reference oscillator (20) and a reference frequency defined according to the intermediate frequency signal (ZF) or a signal derived therefrom. In the receiving part (2), the parameters are adapted in such a way that it makes it possible to directly or indirectly control the oscillation frequency according to the determined frequency deviation (?f).
