摘要:
The invention relates to a receiver for a quadrature-modulated signal, which can be divided into an inphase signal (I) and a quadrature signal (Q). The inphase signal (I) is fed to first and third equalizers (EZ1, EZ3), and the quadrature signal (Q) is fed to second and fourth equalizers (EZ2, EZ4), wherein the first and second equalizers (EZ1, EZ2) each perform a first equalization of the respective signal. An output of the first equalizer (EZ1) is connected to a second input of the fourth equalizer (EZ4), which, by means of a second equalization of the quadrature signal (Q), transmits an equalized quadrature signal (Q2) as a function of the previously fed equalized inphase signal (II) of the first equalizer (EZ1). An output of the second equalizer (EZ2) is connected to the second input of the third equalizer (EZ3), which, by means of a second equalization of the inphase signal (I), transmits an equalized inphase signal (12) as a function of the previously fed equalized quadrature signal (Q1) of the second equalizer (EZ2).
